Gary Edwards's List: Cloud Computing

Amazing must read!  BackBlaze offers unlimited cloud storage/backup for $5 per month.  Now they are releasing the "storage" aspect of their service as an open source design.  The discussion introducing the design is simple to read and follow - which in itself is an achievement.   They held back on open sourcing the BackBlaze Cloud software system, which is understandable.  But they
do disclose a Debian Linux OS running Tomcat over Apache Server 5.4 with JFS and HTTPS access.  This is exciting stuff.  I hope the CAR MLS-Cloud guys take notice. 

Intro: At Backblaze, we provide unlimited storage to our customers for only $5 per month, so we had to figure out how to store hundreds of petabytes of customer data in a reliable, scalable way—and keep our costs low. After looking at several overpriced commercial solutions, we decided to build our own custom Backblaze Storage Pods: 67 terabyte 4U servers for $7,867.

In this post, we’ll share how to make one of these storage pods, and you’re welcome to use this design. Our hope is that by sharing, others can benefit and, ultimately, refine this concept and send improvements back to us. Evolving and lowering costs is critical to our continuing success at Backblaze.

The cloud computing wave is the most dramatic change I have observed in the computing industry since the wave of the Internet. Cloud computing will significantly change data centers and IT organizations as well as the infrastructure and software vendors’ business models. In fact, the cloud computing wave is not just a wave – it is more like a tsunami. What is causing this cloud tsunami?

I start with listing 4 of the Gartner top 10 IT predictions for the next three to five years for cloud computing, software as service (SaaS), data center power/cooling efficiency and open source software. All of these predictions indicate that data center efficiency and cost containment will transform the IT industry over the next 5 years.

This one's for Florian. He's been wondering about mobile computing and that creeping sense of being left out of something big. The desktop is so not happening. It's day has come and gone. Now there is a study out from ABI Research, connecting mobile computing to the future of the Web. Good stuff:

Intro Excerpt:The term "cloud computing" is being bandied about a lot these days, mainly in the context of the "future of the web." But cloud computing's potential doesn't begin and end with the personal computer's transformation into a thin client - the mobile platform is going to be heavily impacted by this technology as well. At least that's the analysis being put forth by ABI Research. Their recent report, Mobile Cloud Computing, theorizes that the cloud will soon become a disruptive force in the mobile world, eventually becoming the dominant way in which mobile applications operate.

Cisco's James Urquhart discusses the NIST definition of Cloud Computing. The National Institute of Technology and Standards is a non regulatory branch of the Commerce Department and is responsible for much of the USA's official participation in World Standards organizations.

This is an important discussion, but i'm a bit disappointed by the loose use of the term "network". I guess they mean the Internet? No mention of RESTfull computing or Open Web Standards either.

Some interesting clips:

...(The NIST's) definition of cloud computing will be the de facto standard definition that the entire US government will be given...In creating this definition, NIST consulted extensively with the private sector including a wide range of vendors, consultants and industry pundants including your truly. Below is the draft NIST working definition of Cloud Computing. I should note, this definition is a work in progress and therefore is open to public ratification & comment. The initial feedback was very positive from the federal CIO's who were presented it yesterday in DC. Baring any last minute lobbying I doubt we'll see many more major revisions.

....... Cloud computing is a pay-per-use model for enabling available, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model promotes availability and is comprised of five key characteristics, three delivery models, and four deployment models.

Sun takes on the problem of interoperability and portability of applications in a world where there will be many many clouds. At the roll out of the Sun Cloud, key executives explain Sun's implementation of Open Cloud API's and what they see as a pressing need for management tools that will allow some standardization across clouds. <br><br>

Sun's Open Cloud API plan is a clean reuse of existing Open Web API's. <br><br>

"..... The underpinning of the Open Cloud Platform that Sun will be pitching to developers is a set of cloud APIs, the creation of which is focused under Project Kenai and which has been released under a Community Commons open source license. Sun wants lots of feedback on the APIs and wants these APIs to become a standard too, hence the open license. These APIs describes how virtual elements in a cloud are created, started, stopped, and hibernated using HTTP commands such as GET, PUT, and POST...."<br><br>

"...... The upshot is that these APIs will allow programmatic access to virtual infrastructure from Java, PHP, Python, and Ruby and that means system admins can script how virtual resources are deployed. The APIs, as co-creator Tim Bray explains in his blog, are written in JavaScript Object Notation (JSON), not XML. The Q-Layer software is a graphical representation of what is going on down in the APIs, and you can moving virtual resources into the cloud with a click of a mouse using the dashboard or programmatically using the APIs from those four programming languages listed above. (PHP support is not yet available, but will be)....."

written by Tim Bray, the Sun Open Cloud API is based entirely on pure and simple "REST":

"....All the resources in the Virtual Data Center (machines, clusters, networks, storage volumes) are "Resources" in the Web sense: that is to say, they are identified by URIs, and operated on by HTTP requests, chiefly GET and POST. Whenever you GET one of these resources, you receive a representation encoded using JSON."

"This walk-through should make it obvious that the cloud interface doesn't constrain the design of the URI space. URIs used for retrieving, creating, and controlling the resources are provided by the system; clients can make no assumptions as to their internal syntax....."

Excellent article on Cloud Computing and the need for an Open API from Dion Hinchcliffe. Solid analysis, deeply linked, with some good graphics:

"....The final outcome of this struggle, as it’s been in many earlier platform battles over personal computer hardware, operating systems, databases, and even the Web itself, will be the result of a fairly predictable and oft-repeated cycle of events (see diagram below) for which a small number of large winners are likely to emerge victorious...."

"When we look back many years from now, it’s probable that cloud computing will be regarded as both a momentous and major change of course in the history of software; many future computing platforms will be created and operated by what seemingly amount to utility companies. While this might seem like a boring future for computing, it’s a necessarily pragmatic evolution as the very size and scope of modern software requires new economic models in order to remain cost effective. Virtually any online application these days has to scale to a few million users as quickly and inexpensively as possible....."

Tom Foremski of Silicon Valley Watcher interviews Bill Coleman of VisiCorp-Sun-BEA fame with questions about the economy and disruptive technologies. Coleman references noted business guru Peter Drucker when he claims that a platform ill be successful if it has three characteristics. First, it has to be able to commoditize a market. Secondly, it has to obey the 10x better/cheaper rule - providing at least ten times the value of what it's displacing. And thirdly, a platform must allow you to add value with custom additions.<br><br>

In the interview, Coleman backs up his assertions with bullseye examples. Clearly his passion is for Cloud Computing, especially the next generation. <br><br>

......"As the cloud computing platform becomes more sophisticated, he predicts that there will be an acceleration in the use of the cloud driven by a "quadruple conversion." Video, audio, and IT data all become IP based, and productivity applications become integrated with social networks.<br><br>

"As we move forward from Web 2.0 to Web 3.0, all your productivity tools become integrated with your social networking, which becomes your business networking. Your mobile life and your online life will become the same. So now the client moves into the cloud and that's when we'll see a dramatic change in the cost structure of computing and of the capabilities you can have."....<br><br>

Good interview. I hope Tom publishes the rest of the session soon.

CIO Magazine has an extensive interview with Craig Mundie, the man responsible for nailing down the next generation of monopolist profits: "You talk about technology waves. What will be the next big wave? What happens in waves is the shift from one generation of computing platform to the next. That platform gets established by a small number of killer apps. We've been through a number of these major platform shifts, from the mainframe to the minicomputer to the personal computer to adding the Internet as an adjunct platform. We're now trending to the next big platform, which I call "the client plus the cloud."
<br><br>
That's one thing, not two things. Today, we've got a broadening out of what people call the client. My 16 years here was in large measure about that. And then we introduced the network. The Internet was a place where you had Web content and Web publishing, but other than being delivered on some of those clients, the two things were somewhat divorced.
<br><br>
The next thing that will emerge is an architecture that allows the application developer to think of the cloud plus the client architecturally as a single thing. In a sense, it is like client/sever computing in the enterprise. It was the homogeneity that existed between some of the facilities at the server and the client end that allowed people to build those applications. We've never had that kind of architectural homogeneity in this cloud-plus-client or Internet-plus-smart-devices world, and I'm predicting that will be the next big thing.

Response to the InformationWeek article "Remaking Microsoft: Get Out of Web Search!". Covers "The Myth of Google Enterprise Search", and the refusal of Google to implement or recognize W3C Semantic Web technologies. This refusal protects Google's proprietary search and categorization algorithms, but it opens the door wide for Microsoft Office editors to totally exploit the end-user semantic interface opportunities. If Microsoft can pull this off, they will take "search" to the Enterprise and beyond into every high end discipline using MSOffice to edit Web ready documents (private and public use). Also a bit about WebKit as the most disruptive technology Microsoft has faced since the advent of the Web.

The question that seems more important than all the rest is “Can I afford to switch vendors?” Let’s consider some examples.

When printers wear out, you can buy new printers from whoever with little concern for switching cost.

If you’re unhappy with your current servers, you can replace them with models from lots of vendors (Sun, Dell, HP, IBM, others) without worrying too much about compatibility (well, you may have some racking and cabling pain); the issues are price, performance, and support.

If you’re grouchy about your OS, you can move between *n*x flavors like Debian, SUSE, and Solaris pretty freely in most (granted, not all) cases; with maybe some deployment and sysadmin pain.

If you’re unhappy with your desktop environment, well too bad, you’re stuck. Your users are too deeply bought into some combination of Outlook calendaring and Excel macros and Sharepoint collab. The price of rebuilding the whole environment is simply too high for most businesses to consider.

If you’re unhappy with your Oracle licensing charges, you probably have to suck it up and deal with it. SQL is a good technology but a lousy standard, offering near-zero interoperability; the cost of re-tooling your apps so they’ll run on someone else’s database is probably unthinkable. Like they say, you date your systems vendor but you marry Larry Ellison.

Murph briefly discusses the history of a Network Operating System, pointing particularly to Microsoft's failed efforts. Then he moves on to comments from Ian Murdock concerning the O'Reilly outline of the rapidly emerging Internet Operating System, that we would otherwise know as <b>The Cloud</b>. The vision behind all this is appealing: have your computer automatically find and use any application you need without the limitations and hassles that go with having to run those applications locally.

Cool! except for Wintel/Lintel devotees whose worldviews are bounded by client-server - because the concept itself embeds the separation of user interaction from processing: meaning that no real implementation of these ideas would need the PC.

Response from Microsoft's Dare Obasanjo to the Tim Bray blog: Get in the Cloud. .. "When it comes to cloud computing platforms, you have all of the same problems described above and a few extra ones. The key wrinkle with cloud computing platforms is that there is no standardization of the APIs and platform technologies that underlie these services. The APIs provided by Amazon's cloud computing platform (EC2/S3/EBS/etc) are radically different from those provided by Google App Engine (Datastore API/Python runtime/Images API/etc). For zero lock-in to occur in this space, there need to be multiple providers of the same underlying APIs. Otherwise, migrating between cloud computing platforms will be more like switching your application from Ruby on Rails and MySQL to Django and PostgreSQL (i.e. a complete rewrite)...."

Although cloud computing vendors are not explicitly trying to lock-in customers to their platform, the fact is that today if a customer has heavily invested in either platform then there isn't a straightforward way for customers to extricate themselves from the platform and switch to another vendor. In addition there is not a competitive marketplace of vendors providing standard/interoperable platforms as there are with email hosting or Web hosting providers.
