SSD and Green IT moving beyond green washing

SSD and Green IT moving beyond green washing

Keeping in mind that there is no such thing as a data or information recession, not to mention that people and data are living longer, there is the need to discuss expanding data footprints. When researching his new article over on SearchSolidstateStorage.com John Hilliard reached out to ask about SSD, Green IT, energy efficiency and effectiveness trends and perspectives (you can read the article and my comments here).

In the past when Green IT and Green storage was mentioned, discussions focused around energy avoidance along with space capacity reduction. While storage efficiency and optimization in the context of space-saving and capacity consolidation are part of Green storage, so too are storage IO consolidation with SSD. For inactive or less frequently accessed data, storage optimization and efficiency can focus on using various data footprint reduction techniques including archive, backup and data protection modernization, compression, dedupe, data management and deletion, along with storage tiering and thin provisioning among others.

SSD and IO consolidation for Green IT and productivity

On the other hand, for active data where performance is important, the focus expands to how to be more effective and boosting productivity with IO consolidation using SSD and other technologies.

Note that if your data center infrastructure is not efficient, then it is possible that for every watt of energy consumed, a watt (or more) of energy is needed to cool. However if your data center cooling is effective with a resulting low or good PUE, you may not be seeing a 1:1 watt or energy used for storage to cooling ratio as was more common a few years ago.

IMHO while reducing carbon footprints is a noble and good thing, however if that is your own focus or value proposition for a solution such as SSD or other Green technologies and techniques including data footprint reduction, you are missing many opportunities.

Have a read of John’s article that includes some of my comments on energy efficiency and effectiveness to support enhanced productivity, or the other aspect of Green IT being economic enabling to avoid missed opportunities.

Give HP storage some love and short strokin

Server and StorageIO industry trends and perspective DAS

Following up from my last post over at InfoStor about metrics that matter, here is a link to a new piece that I did on storage vendors benchmarking and related topics. This new post looked at an storage performance council (SPC1) benchmark that HP did with their P10000 (e.g. 3PAR) storage system under assertions by some in the industry that they were short stroking to meet better performance.

Amazon Web Services (AWS)

I’m surprised some creative technical marketer, blogger or prankster has yet to rework Clarence Carters (e.g. Dr. CC) iconic song into something about storage performance and capacity short strokin.


Ok, nuff said before I get a visit from the HP truth squads, in the meantime, give HP a hug and some love if so inclined.

    How can direct attached storage (DAS) make a comeback if it never left?

    Server and StorageIO industry trend and perspective DAS

    Have you seen or heard the theme that Direct Attached Storage (DAS), either dedicated or shared, internal or external is making a comeback?

    Wait, if something did not go away, how can it make a comeback?

    IMHO it is as simple as for the past decade or so, DAS has been overshadowed by shared networked storage including switched SAS, iSCSI, Fibre Channel (FC) and FC over Ethernet (FCoE) based block storage area networks (SAN) and file based (NFS and Windows SMB/CIFS) network attached storage (NAS) using IP and Ethernet networks. This has been particularly true by most of the independent storage vendors who have become focused on networked storage (SAN or NAS) solutions.

    However some of the server vendors have also jumped into the deep end of the storage pool with their enthusiasm for networked storage, even though they still sell a lot of DAS including internal dedicated, along with external dedicated and shared storage.

    Server and StorageIO industry trend and perspective DAS

    The trend for DAS storage has evolved with the interfaces and storage mediums including from parallel SCSI and IDE to SATA and more recently 3Gbs and 6Gbs SAS (with 12Gbs in first lab trials). Similarly the storage mediums include a mix of fast 10K and 15K hard disk drives (HDD) along with high-capacity HDDs and ultra-high performance solid state devices (SSD) moving from 3.5 to 2.5 inch form factors.

    While there has been a lot of industry and vendor marketing efforts around networked storage (e.g. SAN and NAS), DAS based storage was over shadowed so it should not be a surprise that those focused on SAN and NAS are surprised to hear DAS is alive and well. Not only is DAS alive and well, it’s also becoming an important scaling and convergence topic for adding extra storage to appliances as well as servers including those for scale out, big data, cloud and high density not to mention high performance and high productivity computing.

    Server and StorageIO industry trend and perspective DAS

    Consequently its becoming ok to talk about DAS again. Granted you might get some peer pressure from your trend setting or trend following friends to get back on the networked storage bandwagon. Keep this in mind, take a look at some of the cool trend setting big data and little data (database) appliances, backup, dedupe and archive appliances, cloud and scale out NAS and object storage systems among others and will likely find DAS on the back-end. On a smaller scale, or in high-density rack deployments in large cloud or similar environments you may also find DAS including switched shared SAS.

    Does that mean SANs are dead?
    No, not IMHO despite what some vendors marketers and their followers will claim which is ironic given how some of them were leading the DAS is dead campaign in favor of iSCSI or FC or NAS a few years ago. However simply comparing DAS to SAN or NAS in a competing way is like comparing apples to oranges, instead, look at how and where they can complement and enable each other. In other words, different tools for various tasks, various storage and interfaces for different needs.

    Thus IMHO DAS never left or went anywhere per say, it just was not fashionable or cool to talk about until now as it is cool and trend to discuss it again.

    Ok, nuff said for now.

    Dell is buying Quest software, not the phone company Qwest

    Dell Storage Customer Advisory Panel (CAP)

    For those not familiar with Quest, they are a software company not to be confused with the telephone communications company formerly known as Qwest (aka now known as centurylink).

    Both Dell and Quest have been on software related acquisition initiatives that past few years with Quest having purchased vKernel, Vizoncore (vRanger virtualization backup), BakBone (who had acquire Alavarii and Asempra) for traditional backup and data protection among others. Not to be out done, as well as purchasing Quest, Dell has also more recently bought Appassure (Disclosure: StorageIOblog site sponsor) for data protection, Sonicwall and Wyse in addition to some other recent purchases (ASAP, Boomi, Compellent, Exanet, EqualLogic, Force10, InsightOne, KACE, Ocarina, Perot, RNA and Scalent among others).

    What does this mean?
    Dell is expanding the scope of their business with more products (hardware, software), solution bundles, services and channel partnering opportunities Some of the software tools and focus areas that Quest brings to the Dell table or portfolio include:

    Database management (Oracle, SQLserver)
    Data protection (virtual and physical backup, replication, bc, dr)
    Performance monitoring (DCIM and IRM) of applications and infrastructure
    User workspace management (application delivery)
    Windows server management (migrate and manage, AD, exchange, sharepoint)
    Identify and access management (security, compliance, privacy)

    What does Dell get by spending over $2B USD on quest?

  • Additional software titles or product
  • More software developers for their Software group
  • Sales people to help promote, partner and sell software solutions
  • Create demand pull for other Dell products and services via software
  • Increase its partner reach via existing Quest VARs and business partners
  • Extend the size of the Dell software and intellectual property (IP) portfolio
  • New revenue streams that compliment existing products and lines of business
  • Potential for better rate of return on some of its $12B USD in cash or equivalence

    Is this a good move for Dell?
    Yes for the above reasons

    • Is there a warning to this for Dell?
    Yes, they need to execute, keep the Quest team focused along with their other teams on the respective partners, products and market opportunities while expanding into new areas. Dell needs to also leverage Quest to further its cause in creating trust, confidence and strategic relationships with channel partners to reach new markets in different geographies. In addition, Dell needs to articulate its strategy and positioning of the various solutions to avoid products being perceived as competing vs. complimenting each other.

    Dell Storage Customer Advisory Panel (CAP)

    Dell Storage Customer Advisory Panel (CAP)

    Recently I was asked by Dell to moderate and host their North America storage customer advisory panel (CAP) session (twitter #storagecap) that followed their 2012 storage forum (see comments about 2011 storage forum here) event in Boston (Disclosure Dell covered my trip to Boston).

    This was an interesting event in many ways because it was a diverse group some of whom were long-time EqualLogic and Compellent (both before and post acquisition) customers of various size or customers of Dell who have yet to buy storage from them.

    Dell Storage Customer Advisory Panel (CAP)
    Click on above image for video feed

    Beyond the diversity of types of customers and their relationship with Dell, what also made this event interesting was that it was live streamed with professional produced video and audio in addition to twitter and other social media coverage. However what made the event even more interesting IMHO was the fact that being a live event (watch replay here) in video with audio as well as on twitter, the attendees were urged to speak freely with conversation among themselves providing feedback and commentary for Dell.

    Sure there were songs of praise when and were deserved, however unlike some made for social media vendor events that tend to be closer to sales pitches, this event also included some tough love feedback and comments for Dell, their products, services and events planner.


    Dell Storage CAP illustrators aka @ThinkLink

    Oh, did I mention that other than some members from the Dell social media team (@dell_storage) who were in the room to help facilitate and coordinate the event itself, the real discussions were free and independent of Dell employees (other than to remind not to avoid going into NDA land while live on the video and audio feed). Dell had @ThinkLink doing live illustrations capturing as images the discussion themes, topics and points of interests during the events that you can see examples of in the following images.

    Dell Flickr images from the Storage CAP session

    Kudos to Dell for having the courage, conviction and confidence to have a customer advisory panel event live streamed, that also allowed the attendees to speak their mind free of a script or talking points guide. The session included having each participant taking a turn of putting themselves in the general managers chair and saying what they would do, why, and how they would address customers and prospects.
    After all, its one thing to sit in the cheap seats, playing arm-chair quarterback saying what you want, it’s another saying why you need it, what the priority and impact are or would be and how to get the message to the customer. Some of the topics covered included Appassure for data protection, Compellent, EqualLogic and other recent acquisitions, products, service, support and community forums.

    Thanks to all who participated including @ThinkLink (illustrators), Dell Storage social media team (@dell_storage), Alison Krause (@AlisonDell), Gina Rosenthal (@gminks), Michelle Richard (@meesh_says) and particularly the participants Pete Koehler (@petergavink), Roger Lund (@rogerlund), Luigi Danakos (@nerdblurt), Dan Marbes (@danmarbes), Jeff Hengesbach (@jeffhengesbach), Steve Mickeler (@shmick), Ed Aractingi (@earactingi) and Dennis Heinle (@dheinle).

    Enabling Bitlocker on Microsoft Windows 7 Professional 64 bit

    Enabling Bitlocker on Microsoft Windows 7 Professional 64 bit
    Updated 6/24/18

    A while back, I added a new laptop that required Enabling Bitlocker on Microsoft Windows 7 Professional 64 bit. At that time some of my other devices run Windows 7 Ultimate 32 bit with Bitlocker security encryption enabled (since upgraded to various Windows 10 editions). However back then, I ran into a problem getting Bitlocker to work on the 64 bit version of Windows 7 Professional.

    Yes I know I should not be using Windows and I also have plenty of iDevices and other Apple products lying around. Likewise to the security pros and security arm-chair quarterbacks I know I should not be using Bitlocker, instead using Truecrypt of which I have done some testing and may migrate too in the future along with self-encrypting device (SED).

    However lets stay on track here ;).

    Lenovo Thinkpad X1 Gen6

    The problem that I ran into with my then new Lenovo X1 was that it came with Windows 7 Professional 64 bit, which has a few surprises when trying to turn on Bitlocker drive encryption. Initializing and turning on the Trusted Platform Module (TPM) management was not a problem, however for those needing to figure out how to do that, check out this Microsoft TechNet piece.

    The problem was as simple as not having a tab and easy way to enable Bitlocker Drive Encryption with Windows 7 Professional 64 bit. After spending some time searching around various Microsoft and other sites to figure out how to hack, patch, script and do other things that would take time (and time is money), it dawned on me. Could the solution to the problem be as simple as upgrading from the Professional version of Windows 7 bit to Windows 7 Ultimate?

    Update: 6/25/18

    While this post is about Windows 7, there are some new challenges with Windows 10 bit locker and removable devices including USB. These new issues are tied to Windows 10 running in BIOS instead of UEFI boot mode.

    Here are some additional Windows 10 Bitlocker related resources:

  • Via Microsoft: Bitlocker Frequently Asked Questions
  • Via Microsoft: Bitlocker Overview and Requirements
  • Via Intel: Converting Windows Installation from BIOS to UEFI

    • Microsoft Windows 7 via amazon
    Windows 7 image courtesy of Amazon.com

    The answer was going to the Microsoft store (or Amazon among other venues) and for $139.21 USD (with tax) purchase the upgrade.

    Once the transaction was complete, the update was automatically and within minutes I had Bitlocker activated on the Lenovo X1 (TPM was previously initiated and turned on), a new key was protected and saved elsewhere, and the internal Samsung 830 256GB Solid State Device (SSD) initializing and encrypting. Oh, fwiw, yes the encryption of the 256GB SSD took much less time than on a comparable Hard Disk Drive (HDD) or even an HHDD (Hybrid HDD).

    Could I have saved the $139.21 and spent some time on work around? Probably, however as I did not have the time or interest to go that route, however IMHO for my situation it was a bargain.

    Sometimes spending a little money particular if you are short on or value, your time can be a bargain as opposed to if you are short on money however long on time.

    I found the same to be true when I replaced the internal HDD that came with the Lenovo X1 with a Samsung 256GB SSD in that it improved my productivity for writing and saving data. For example in the first month of use I estimate easily 2 to three minutes of time saved per day waiting on things to be written to HDDs. In other words 2 to three minutes times five days (10 to 15 minutes) times four weeks (40 to 60 minutes) starts to add up (e.g. small amounts or percentages spread over a large interval add up), more on using and justifying SSD in a different post.

    Microsoft Windows 7 Ultimate

    If your time is not of value or you have a lot of it, then the savings may not be as valuable. On the other hand, if you are short on time or have a value on your time, you can figure out what the benefits are quite quickly (e.g. return on investment or traditional ROI).

    Where To Learn More

    Learn more about Windows, Bitlocker and related topics

    Additional learning experiences along with common questions (and answers), as well as tips can be found in Software Defined Data Infrastructure Essentials book.

    Software Defined Data Infrastructure Essentials Book SDDC

    What This All Means

    The reason I bring the topic of time and money into this discussion about Bitlocker is to make a point that there are situations where spending some time has value such as for learning, the experience, fun or simple entertainment aspect, not to mention a shortage of money. On the other hand, sometimes it is actually cheaper to spend some money to get to the solution or result as part of being productive or effective. For example, other than spending some time browsing various sites to figure out that there was an issue with Windows 7 Professional and Bitlocker, time that was educational and interesting, the money spent on the simple upgrade was worth it in my situations. While many if not most of you have since upgraded to Windows 8 or Windows 10, some may still have the need for Enabling Bitlocker on Microsoft Windows 7 Professional 64 bit.

    NetApp on rough ground, or a diamond in the rough?

    Storage I/O Industry Trends and Perspectives

    In case you missed it, NetApp announced their most recent quarterly earnings a few weeks ago which in themselves were not bad. However what some of their competition jumping up and down for joy while others are scratching their heads is the forward-looking guidance given by NetApp.

    NetApp can be seen as being on rough ground given their forward-looking guidance over the next year which could be seen as either very conservative, or an admission that they are not growing as fast as some of their competitors are challenging them.

    Reading between the lines, looking at various financial and other resources in addition to factoring in technology items, there is more to NetApp then meets the eye and current stock price or product portfolio.

    For example, NetApp is sitting on over $4 Billion USD cash that they could use for an acquisition, buying back stock, launching a major sales and marketing initiative to expand into new or adjacent markets or other activities. Speaking of acquisitions, NetApp has done some in the past including Spinnaker, which is now integrated with Ontap (e.g. clustering), Topio, Decru (security encryption) and Onaro (DCIM and IRM management software tools). More recently, NetApp has acquired Bycast (archiving and policy storage management software), Akorri (capacity management and DCIM and IRM software) and Engenio. NetApp is also maintaining good margins via both direct, channel and OEM activities while launching new products such as the channel and SMB focused FAS 2220.

    Its arguable depending upon your point of view (or who you for or are a fan of) if NetApp has all the right product pieces now, in the works, or on their radar for acquisitions. Assuming that NetApp has the pieces, they also need to move beyond selling simply what is on the truck or what is safe and comfortable or perhaps easy to sell. This is not to say that NetApp is not being effective in selling what they have and pushing the envelope, however keeping in mind who their main competitor is, the old sales saying of being able to sell ice to an Eskimo comes to mind.

    Two companies on parralel tracks offset by time: EMC and NetApp

    In the case of NetApp, when the competition makes an issue about scalibility or performance of their flagship storage systems FAS and Ontap storage software, change the playing field leveraging all the tools in their portfolio. NetApp like EMC before them is figuring out how to sell via different channels or venues their complete portfolio with a mix of direct, channel and OEM. After all, it seems like only yesterday that EMC was trying to figure out where and when to sell CLARiiON (e.g. now VNX) as opposed to avoiding competing with the Symmetrix (aka now the VMAX) not to mention expanding from a direct to channel and OEM model. Perhaps NetApp can continue to figure out how to leverage more effectively the Engenio E series for big bandwidth beyond their current OEMs. NetApp can also leverage their existing partners who have embraced Bycast (aka StorageGrid) while finding new ones.

    The reality is that NetApp is being challenged by EMC who is moving down market into some of NetApp’s traditional accounts along with in the scale-out NAS and big data sectors. This is where NetApp can leverage their technical capabilities including people combined with some effective sales and marketing execution to change the playing field vs. responding to EMC and others.

    NetApp has many of the pieces, parts, products, people, programs and partners so now how can they leverage those to expand both their revenues, as well as support margin to grow the business, unless they are looking to be acquired.

    I still subscribe that NetApp and EMC are two similar companies on parallel tracks offset by time, by about a decade or decade and a half.

    Storage I/O Industry Trends and Perspectives

    Thus, IMHO NetApp is a diamond in the rough, granted I am guessing EMC and some others do not see it that way. However, there was a time when EMC was seen as a diamond in the rough while others discounted that notion, particularly an Itty Bitty Manufacturing company from New York who is now focusing on services among other things.

    Keep in mind however, diamonds can also be lost or taken as well as there can be fake gems.

    Green IT deferral blamed on economic recession might be result of green gap

    Storage I/O Industry Trends and Perspectives

    I recently saw a comment somewhere that talked about Green IT being deferred or set aside due to lack of funding because of ongoing global economic turmoil. For those who see Green IT in the context of the green washing efforts that requiring spending to gain some benefits that I can understand. After all, if your goal is to simply go and be or be seen as being green, there is a cost to doing that.

    With tight or shrinking IT budgets, there are other realities and while organizations may want to do the right thing helping the environment, however that is often seen as overhead to financial conscious management.

    On the other hand, turn the green washing messaging off or at least dial-it back a bit as has been the case the past couple of years.

    Expand the Green IT discussion or change it around a bit from that of being seen or perceived as being green by energy efficiency or avoidance to that of effectiveness, enhanced productivity, doing more with what you have or with less and there is a different opportunity.

    That opportunity is to meet the financial and business goals or requirements that as a by-product help the environment. In other words, expand the focus of Green IT to that of economics and improving on resource effectiveness and the environment gets a free ride, or, Green gets self-funded.

    The Green and Virtual Data Center Book addressing optimization, effectivness, productivity and economics

    The challenge is what I refer to as the Green Gap, which is the disconnect between what is talked about (e.g. messaging) and thus perceived to be Green IT and where common IT opportunities exist (or missed opportunities have occurred).

    Green IT or at least the tenants of driving efficiency and effectiveness to use energy more effectively, address recycling and waste, removable of hazardous substance and other items continues to thrive. However, the green washing is subsiding and overtime organizations will not be as dismissive of Green IT in the context of improving productivity, reducing complexity and costs, optimization and related themes tied to economics where the environment gets a free ride.

    Why FC and FCoE vendors get beat up over bandwidth?

    Storage I/O Industry Trends and Perspectives

    Have you noticed how Fibre Channel (FC) and FC over Ethernet (FCoE) switch and adapter vendors and their followers focus around bandwidth vs. response time, latency or other performance activity? For example, 8Gb FC (e.g. 8GFC), or 10Gb as opposed to latency and response time, or IOPS and other activity indicators.

    When you look at your own environment, or that of a customers or prospects or hear of a conversation involving storage networks, is the focus on bandwidth, or lack of it, or perhaps throughput being a non-issue? For example, a customer says why go to 16GFC when they are barely using 8Gb with their current FC environment.

    This is not a new phenomenon and is something I saw when working for a storage-networking vendor who had SAN, MAN and WAN solutions (E.g. INRANGE). Those with networking backgrounds tended to focus on bandwidth when discussing storage networks while those with storage, server or applications background also look at latency or IO completion time (response time), queuing, message size, IOPs or frames and packets per second. Thus there are different storage and networking metrics that matter that are also discussed further in my first book Resilient Storage Networks: Designing Flexible Scalable Data Infrastructures.

    When I hear a storage networking vendor talk about their latest 16GFC based product I like to ask them what is the biggest benefit vs. 8GFC and not surprisingly, the usual response is like twice the bandwidth. When I ask them about what that means in terms of more IOPS in a given amount of time, or reduced IO completion time, lower latency, sometimes I often get the response along the lines of Yeah, that too, however it has twice the bandwidth.

    Ok, I get it, yes, bandwidth is important for some applications, however so too are activity measured in IOPS, transactions, packets, frames, pages, sequences and exchanges among other units of measure along with response time and latency (e.g. different storage and networking metrics that matter).

    What many storage networking vendors actually get, however they don’t talk about it for various reasons, perhaps because they are not be asked about it, or engaged in the conversation is that there is an improvement in response time in going from such as 8GFC to 16GFC. Likewise, there can be improvements in response time in addition to the more commonly discussed bandwidth.

    If you are a storage networking switch, adapter or other component vendor, var or channel partner expand your conversation to include activity and response time as part of your value proposition. Likewise, if you are a customer, ask your technology providers to expand on the conversation of how new technologies help in areas other than bandwidth.

    How much SSD do you need vs. want?

    Storage I/O Industry Trends and Perspectives

    I have been getting asked by IT customers, VAR’s and even vendors how much solid state device (SSD) storage is needed or should be installed to address IO performance needs to which my standard answer is it depends.

    I also am also being asked if there is rule of thumb (RUT) of how much SSD you should have either in terms of the number of devices or a percentage; IMHO, the answer is it depends. Sure, there are different RUTs floating around based on different environments, applications, workloads however are they applicable to your needs.

    What I would recommend is instead of focusing on percentages, RUTs, or other SWAG estimate’s or PIROMA calculations, look at your current environment and decide where the activity or issues are. If you know how many fast hard disk drives (HDD) are needed to get to a certain performance level and amount of used capacity that is a good starting point.

    If you do not have that information, use tools from your server, storage or third-party provider to gain insight into your activity to help size SSD. Also if you have a database environment and are not familiar with the tools, talk with your DBA’s to have them run some reports that show performance information the two of you can discuss to zero in hot spots or opportunity for SSD.

    Keep in mind when looking at SSD what is that you are trying to address by installing SSD. For example, is there a specific or known performance bottleneck resulting in poor response time or latency or is there a general problem or perceived opportunity?

    Storage I/O Industry Trends and Perspectives

    Is there a lack of bandwidth for large data transfers or is there a constraint on how many IO operations per second (e.g. IOPS) or transaction or activity that can be done in a given amount of time. In other words the more you know where or what the bottleneck is including if you can trace it back to a single file, object, database, database table or other item the closer you are to answering how much SSD you will need.

    As an example if using third-party tools or those provided by SSD vendors or via other sources you decide that your IO bottleneck are database transaction logs and system paging files, then having enough SSD space capacity to fit those in part of the solution. However, what happens when you remove the first set of bottlenecks, what new ones will appear and will you have enough space capacity on your SSD to accommodate the next in line hot spot?

    Keep in mind that you may want more SSD however what can you get budget approval to buy now without having more proof and a business case. Get some extra SSD space capacity to use for what you are confident can address other bottlenecks, or, enable new capabilities.

    On other hand if you can only afford enough SSD to get started, make sure you also protect it. If you decide that two SSD devices (PCIe cache or target cards, drives or appliances) will take care of your performance and capacity needs, make sure to keep availability in mind. This means having extra SSD devices for RAID 1 mirroring, replication or other form of data protection and availability. Keep in mind that while traditional hard disk drive (HDD) storage is often gauged on cost per capacity, or dollar per GByte or dollar per TByte, with SSD measure its value on cost to performance. For example, how many IOPS, or response time improvement or bandwidth are obtained to meet your specific needs per dollar spent.

    Only you can prevent cloud data loss

    Storage I/O trends

    Some of you might remember the saying from Smokey the bear, only you can prevent forest fires and for those who do not know about that, click on the image below.

    The reason I bring this up is that while cloud providers are responsible (see the cloud blame game) is that it is also up to the user or consumer to take some ownership and responsibility.

    Similar to vendor lock-in, the only one who can allow vendor lock in is the customer, granted a vendor can help influence the customer.

    The same theme applies to public clouds and cloud storage providers in that there is responsibility of providers along with government and industry regulations to help protect consumers or users. However, there is also the shared responsibility of the user and consumer to make informed decisions.

    What is your perspective on who is responsible for cloud data protection?
