Cloudify your Enterprise Data Center: Two emerging models

With recent advancements and announcements in the Industry, its clear that there are two emerging models for taking an Enterprise data center into the Clouds.

The first approach "the private cloud", requires an enterprise to purchase "Cloud in a Box" software such as vCloud and vSphere along with virtualization software provided by vendors like VMware. VMware is going a few steps further up in the stack with acquisition of SpringSource which will enable their existing and future customer base to seamlessly develop, deploy and manage applications in VMware based Clouds. The Private Cloud is applicable when the cloud is confined to an enterprise owned data center and provides a great way to scale the existing virtualized customer data centers by adding the flexibility and utilization efficiencies of a Cloud. Vendors like Rackspace and GoGrid are building Managed Private Clouds for their enterprise customers using this approach.

While a private cloud offers the CIO the benefits of a Cloud architecture, unleashing resource management, utilization, and on demand scaling capabilities, it still does not meet the goals of a pure Cloud as it only offers limited elasticity and does not eliminate capex. The enterprise still needs to own and manage all the resources. Werner Vogel has explained this very eloquently in his blog here. Nevertheless, it enables CIOs to better manage existing resources by means of metering, billing usage, and charge back to other business units.

The second emerging approach is that of Hybrid architectures where enterprises can extend their existing IT infrastructure to leverage on-demand resources of an external cloud thus adding scalability on demand. The enterprise continues to utilize their existing data center and augment it by offloading certain types of usage to an external cloud. They can also use this approach for handling the occasional burst loads, and not having to over provision their own infrastructure to meet peak demand. This approach is in line with Amazon's announcement of their Amazon Virtual Private Cloud (Amazon VPC). While it has its limitations, its a solid first step in this direction.

The two approaches are complimentary, and can be combined towards building Hybrid Clouds where resources are moved between multiple Clouds seamlessly. However, I see a need for standardization of protocols and APIs offered by the clouds from different vendors before we can offer this level of flexibility to all users.

Cloud Computing Services Officer

So Long CIO, Welcome CCSO.

How cool is that for a Job Title?

Seems like the CIO job at a company of managing business's information is expanding towards one that would require additional responsibility of  designing IT operations as services that can be consumed and paid for internally and externally. CCSOs might oversee the use of subscription services and might design their systems and networks to be used by others for subscription purposes.

Cant agree more with Mark Everett Hall of CompterWorld that the arrival of CCSOs (or whatever they end up being called) will be the ultimate recognition by business that IT is less and less about systems, software or even the information they support, and more about the services those tools bring to an organization.

Cloud Computing for the White House?

Ok, Now we are talking!

Oh well, we know the Obama team is quite technology savvy and want to run the administration on the state of the art computer technologies. As an example, Obama campaign website used MySQL on the backend. 

So then, can Cloud Computing benefits lure the administration? Security and Technology experts discuss on national public radio  if Cloud Computing will work for the White House and how their computers should run.  Kevin L. Jackson further muses if the Obama Administration should use Cloud Computing.  He believes that Cloud Computing technology can indeed be used to implement the recommendations made by Center for Strategic and International Studies (CSIS)  that recently released the Commission on Cybersecurity for the 44th Presidency.

Wired Planet: Cloud Computing Interoperability

In some of my earlier Blog entries, I have mentioned the need for Cloud Interoperability, in order to prevent cloud vendor lockin. I am glad to see some industry movement in that direction. Cloud Computing Interoperability Forum (CCIF) was formed recently and is a group of industry stakeholders that are active in cloud computing. Its objective is to enable a global cloud computing ecosystem whereby organizations are able to seamlessly work together for the purposes for wider industry adoption of cloud computing technology and related services. A key focus will be placed on the creation of a common agreed upon framework / ontology that enables the ability of two or more cloud platforms to exchange information in an unified manor.

Encourage everybody to contribute and participate as appropriate.

Save money with Open Storage

Open Storage helps you save time and money for Web-scale Applications.

Want Proof?

Check this excellent  benchmark for Web 2.0 run on Sun Storage 7410 (aka AmberRoad) and CMT technology based Sun Fire T5120 servers.

Its also evident from the benchmark data that you don't suffer a performance penalty for using NAS.  There is a fairly common impression that performance could/would be slower than DAS, this shows that it's just not true with this environment.

System Processors Results

EUCALYPTUS : Open Source Cloud Infrastructure, The Skies are Opening!

Last week I attended a fantastic talk on EUCALYPTUS at a cloud computing meetup.  The presentor Rich Wolski, is a a professor in the Computer Science Department at the University of California, Santa Barbara.  He created EUCALYPTUS, an open source cloud computing implementation, that is interface compatible with Amazon EC2.  It was a great educational talk, very relevant to the budding cloud computing industry. Rich Wolski put in perspective the popularity of Cloud Computing when he mentioned that the term "Cloud Computing" was only coined about a year ago, by Google on Oct. 8 2007 in a press release.  Today after 1 year and 1 month, a google search on "cloud computing" gives ~9 million results! This explosive growth in cloud computing got Prof. Rich Wolski interested in the subject for research and gave birth to the project EUCALYPTUS.

EUCALYPTUS is an acronym and expands to: Elastic Utility Computing Architecture Linking Your Programs To Useful Systems. The infrastructure is designed to support multiple client-side interfaces besides EC2. It is implemented using commonly-available Linux tools and basic Web-service technologies making it easy to install and maintain.

The fig. below illustrates the EUCALYPTUS architecture.

 


The Cloud Controller implements all the gory details of the Cloud backend provisioning, whereas the Client side API Translator emulates a Cloud interface like EC2. This design makes EUCALYPTUS modular and extensible to emulate clouds other than EC2. Eg., EUCALYPTUS plans to emulate the Google Apps Engine in the near future by adding yet another API Translation layer. In its current version available today, EUCALYPTUS translator is built to EC2 WSDL published by Amazon and is 100% interface compatible with EC2. When RightScale management and monitoring tools connected with EUCALYPTUS, they were not able to identify any difference between EC2 and EUCALYPTUS.

Security and authentication mechanism is very similar to EC2 except for its without a credit card. User signup is web based and ssh key generation and installation is implemented just like EC2. Since there are no published administration and accounting tools published by EC2, EUCALYPTUS defines its own tools for user management and cloud management.

 When EUCALYPTUS project was launched, the objective was to keep it simple, extensible, easy to install and maintain, and build it on widely available and popular open source technologies. Another objective was to ensure that it is a cloud indeed, given there has been a lot of confusion about what a Cloud really is or not is. To ensure that, the team decided to emulate an existing cloud and made the following design decisions:

  • EUCALYPTUS would be interface compatible with Amazon EC2 and S3
  • It  would work with command line tools directly from Amazon without any modifications
  • It would leverage exisitng EC2 value added services like RightScale

Given EUCALYPTUS was an open source project and would need to run on any hardware without prior knowledge of the underlying infrastructure, it was also designed  to function as a software overlay such that existing installation is not violated too much and no assumptions are made about the hardware.

Some of the Goals of EUCALYPTUS were:

  • Foster research in elastic/cloud/utility computing
  • Experimental vehicle prior to buying commercial services from EC2 and other clouds
  • Providing a debugging and development platform for EC2 and other clouds
  • Provide a basic cloud platform for the open source community. Might evolve into a Linux experience..
  • Not designed as a replacement technology for EC2 or other commercial cloud services. In its current form, it can scale upto 1000 nodes.

Some of the biggest challenges addressed by Rich Wolski and his team of 5 research students around building EUCALYPTUS were:

  • Extensibility
  • Client side interface (modular design so that its compatible with EC2 and other clouds)
  • Networking
  • Security
  • Packaging and Installation (One click install)

EUCALYPTUS is hosted as a public cloud and its free for use. However, only installed images can be run and usage is limited to 6 hours. EPC (EUCALYPTUS Public Cloud) configuration consists of:

  • 8 Pentium Xeon processors (3.2 GHz)
  • 2.5 GB of memory per image
  • 3.6GB disk space
  • 1GB ethernet interconnect
  • Linux 2.6.18-xen-3.1
  • Xen 3.2

Yes, its as big as an electron in the EC2 cloud. So clearly, even though its not a replacement for a commercial cloud, cloud vendors could learn a lot from its implementation if they wish to build their own cloud. Developers and end users could use it for testing and debugging purposes before deploying it on a real cloud. Given the popularity of cloud Computing, it could be the next Linux experience! Who knows.

IMHO, its a fabulous piece of work done by a team of 7 engineers at UCSB, using open source technologies, working with a limited budget in a duration of about 6-8 months. Check it out!!

Sun's Cloud Computing Portfolio

Update: Sun has expanded its Cloud Computing portfolio with the recent acquisition of Qlayer, a cloud computing company that automates the deployment and management of both public and private clouds.  The Q-layer organization, based in Belgium, is now part of Sun's Cloud Computing business unit which develops and integrates cloud computing technologies, architectures and services.

Cloud computing is about managing petascale data. Sun's server and storage systems can radically improve the data-intensive computing emerging in the cloud. Some clouds are closed platforms that lock you in. Sun's open source philosophy and Java principles form the core of a strategy that provides interoperability for large-scale computing resources. Sun's virtualization solutions for advanced high-performance computing deployments are integrated with Solaris and Web 2.0 technologies such as Java and MySQL.

Check out Sun's Cloud Computing Porfolio below:

  • MySQL is almost the defacto database of choice powering the web-scale next-generation of database driven web applications in the cloud. Cloud computing solutions for MySQL makes it easy to develop, deploy, and manage your new and existing MySQL-backed applications in a virtual computing environment. The MySQL Enterprise for Amazon EC2 subscription is a comprehensive offering of database software and production support to deliver applications on Amazon EC2 with optimal performance, reliability, security, and uptime. For the first time, organizations can now cost-effectively deliver database driven web-scale computing in the "cloud", fully backed by the MySQL database experts at Sun. You can learn more about it here


  • The Webstack from Sun is the optimized open source software stack and is bundled with latest release of OpenSolaris 2008.11. It is pre-configured to have the most popular applications (Apache, PHP, MySQL) to work seamlessly out of a Solaris box. By using Solaris with these binaries in a Cloud, you can enjoy the best levels of performance, while also reducing your time-to-service.
  • Performance is one of the key metrics that users are skeptical about in the cloud. White its not a critical criteria, they still want to be able to profile their applications running in the cloud. Netbeans  provides plugins to profile your application on Amazon EC2. Check out the steps here on how to use Netbeans for profiling your application in the Cloud. You can learn more on this at the Cloud Computing Bootcamp on Nov. 19 2008.  

  • Virtualization is key to enabling a Cloud Computing environment. The Sun xVM portfolio offers a simple and efficient way to leverage a heterogeneous, virtualized environment:
    • xVM Ops Center Discover, provision, update, and manage globally dispersed IT environments from one console
    • xVM VirtualBox Build, test, and run applications on one desktop or laptop for multiple OS platforms side by side
    • xVM Server Securely and reliably virtualize systems and services in a Windows, Solaris OS, or Linux environment
    • Sun VDI Software Securely access a virtual desktop from nearly any client on the network

Further, Solaris 10 includes the Containers technology which is an implementation of operating system level virtualization technology first made available in 2005 as part of Solaris 10. A Solaris Container is the combination of system resource controls and the boundary separation provided by zones. Zones act as completely isolated virtual servers within a single operating system instance. By consolidating multiple sets of application services onto one system and by placing each into isolated virtual server containers, system administrators can reduce cost and provide all the same protections of separate machines on a single machine, hence making it a perfect technology for the Clouds.

  • Besides the product portfolio, Sun is also offering services in the Cloud Computing space.
    • Zembly is a service from Sun hosted on Network.Com which is a place to create social applications, together.  At Zembly, you easily create and host social applications of all shapes and sizes, targeting the most popular social platforms on the web like Facebook, Meebo, iPhone, Google Gadgets etc. And, you do it along with other people, using just your browser and your creativity, and working collaboratively with others.
    • Project Kenai is the foundation for the connected developer of tomorrow. It allows you to freely host your open source projects and code. Find and collaborate with developers of like mind and passion from around the globe.
    • Project SocialSite, is an open source ( CDDL/GPL2) project for building Widgets and Web Services that make it easy for you to add social networking features to your existing web sites, including the ability to run OpenSocial Gadgets and have them backed by the same social graph.
    • Project Caroline is an advanced R&D project at Sun Microsystems. It is a hosting platform for development and delivery of dynamically scalable Internet-based services. It is designed to serve an emerging market of small and medium sized software-as-a-service (SaaS) providers.


  • Sun is offering Open Solaris on Amazon EC2 OpenSolaris, which comes with tools such as ZFS and Dynamic Tracing (D-Trace), are offered for free, in contrast to some Linux offerings that cost money. ZFS allows instant rollback and continual check-summing capabilities, something developers have found lacking in the EC2 platform.  In addition, Sun is offering several popular EC2 images like Drupal, Roby on Rails, Apache, Tomcat etc. For the entire list, click here.


  • Sun is running several promotions for  hosting Facebook and OpenSocial applications on OpenSolaris free for 1 year with some of our cloud computing partners like Joyent. For more details, check out our Startup Essentials program.

Stay tuned for more to come from Sun in this space.

My 2 cents on Microsoft Azure

Microsoft recently announded their Cloud offering called Azure. Azure is more of a PaaS Windows cloud, offering their proprietary closed Winows products  as a service. Seems to me like that traditional Software as a Service (Saas) model. Does not REALLY excite me! Marketing dollars well spent though in picking up the name Azure, meaning "clear cloudless sky". In addition, they have not yet announced anything around SLAs and price for the service, key for successful adoption of cloud based computing.

Yahoo announced yesterday their own PaaS Y!Open platform based on OpenSocial APIs that is geared more towards targeting Social networking audience unlike Azure. This is more interesting to me as they will immediately be able to capture new developers and expand on their current echosystem.

But yes, Azure is offering more than what Google Apps Engine offers today. To me, it would be interesting to see what M$ offers around industry standard APIs like OpenSocial which is how they can attract more of the Next-gen developers building mashup services around their PaaS. They seem to have endorsed OpenSocial anyways.

Facebook has gone up from 27 million users to 140 million users after opening up their Facebook API to developers in the last one year with 40 thousand third party applications hosted on facebook. Now thats revolution. Its all about expanding the echosystem of your developers in this era of internet computing and thus monopolising the market/making yourself indispensible. Its all about the open APIs, rather than spinning your own proprietary API clouds like Azure. 

Web-scale and Cloud Computing open APIs is almost like the Open Source model which we have all come to love and thrive on. Stay tuned on my next blog on Open Web Identity leading to Identity platforms and Open Social Networks.

Its all about Evolution: IDC Research survey results on Cloud Computing

IDC made a Press Release this week on a research survey on Cloud Computing adoption in the next five years. Good to see some numbers backing the hype.

As per IDC, Cloud computing is reshaping the IT marketplace, creating new opportunities for suppliers and catalyzing changes in traditional IT offerings. Over the next five years, IDC expects spending on IT cloud services to grow almost threefold, reaching $42 billion by 2012 and accounting for 9% of revenues in five key market segments. More importantly, spending on cloud computing will accelerate throughout the forecast period, capturing 25% of IT spending growth in 2012 and nearly a third of growth the following year.

In addition, they added that to succeed, cloud services providers need to address a mixture of traditional and cloud concerns. According to survey respondents, the two most important things a cloud services provider can offer are competitive pricing and performance level assurances. These are followed by the ability to demonstrate an understanding of the customer's industry and the ability to move cloud services back on-premises if necessary.

Test Drive MySQL on Solaris 10 for FREE in EZQual Virtual Labs. No Installation, No Cost

MySQL is the defacto database of choice for most WebScale and Cloud Computing deployments.

Every day you go to website like Facebook, CraigsList , eBay, Google, PriceGrabber, Yahoo!, and Zappos, you are touching a page that  uses MySQL.
MySQL's popularity is due in large part to its flexibility. MySQL supports over 20 platforms and scales to handle terabytes of data. And, because MySQL is open source, it can be customized to an application's unique specifications. This flexibility has two-fold benefits for ISVs: MySQL is better able to address their applications' specific needs and it won't impose restrictions on their future development.

Through the Sun Partner Advantage Program(SPA) , ISVs can now leverage Sun's entire portfolio of offerings - including MySQL. The SPA Program connects ISVs with free or deeply discounted technology offerings as well as marketing and sales engagement opportunities so they can deliver their solutions and services to an expanded market.

We have set up a secure, remote, on-line test facility called the EZQual Virtual Lab! designed to make it easier for ISVs to develop, test and qualify applications on Solaris 10 or OpenSolaris and MySQL for free! ISVs can join and get their applications tested and ready for MySQL today in our EZQual lab for Free. The EZQual Virtual Lab features pre-installed SPARC or x86 processor-based Sun servers with Sun Studio Development Tools, Java SE, Sun's Cool Stack, MySQL, Solaris 10, OpenSolaris and more. These servers can be accessed conveniently with Sun's Secure Global Desktop Software.  This is as convenient as it gets. No servers to install, no OS installations; you're ready to go and can sign up today!

Cloud Computing and Beyond: The Web Grows up (Finally!)

I recently attended a conference titled "Cloud Computing and Beyond: The Web Grows up (Finally!) hosted by SDForum in Santa Clara. It was a good informative conference with views presented from the enterprise world like Sun, IBM, HP, SAP, Salesforce, from Cloud providers/vendors like Joyent, GoGrid, Nirvanix, from Cloud Application providers like Mashery, PBWiki and several VCs.

Lew Tucker of Sun gave a fine presentation calling out that one of the major driver of Cloud Computing is the Web APIs.

Russ Daniels of HP called out that the economics of Cloud computing will have a huge influence on what Clouds do and the value will be in targeting new markets, driving higher margins, differentiation and increased share in the market.

Jayashree of IBM talked about the IBM Cloud Computing centers around the world to enable cloud providers use IBM technologies to build clouds and get their feedback as well.

There was an interesting Panel discussion on When to use the Cloud and When Not To. Participants included Joyent, Nirvanix, Elastra, eComputer. Most agreed that Cloud Computing changes the cost and consumption model for applications and services moving from a Capex to an Opex model.

Some of the chalenges of Cloud Computing that were discussed in another panel included lock-in to specific cloud provider proprietary APIs, hence a need for Cloud API standardization. In the absence of such next-gen standard APIs, there is plenty of oportunity for startups here to deliver software that would make migration of applications from one cloud vendor(say EC2) to another (say Google App engine) seamless.

The VCs showed confidence in Cloud Computing and suggested that it is here to stay. It is not necessarily the next revolution but evolution of some of the internet technologies that have been around for decades like Grid computing and more recent ones like Utility computing and SaaS.

Bottomline was that those who learn to do Cloud Computing profitably will survive in the long term, especially in view of the economic recession.

Zembly dives into Elections

Zembly team has deployed a new application on Zembly called myPicks U.S. Election 2008.

Use this to voice your opinion on the campaign issues being debated in the U.S. Presidential Election - wherever you are in the world.

You can launch the game from: http://zembly.com/mypicksus/

While the frontend is running on Network.Com, the backend including the MySQL server is running on EC2 and data resides on S3

The game is available as a Facebook and MySpace App.

Some cool mashup. They use Dapper to convert some Election related URLs into a API and feed it into the Zembly code/widgets.

Good CloudComputing stuff, check it out!

Camping in the Cloud - An Unconference

Hi, This is Alka Gupta of Sun Microsystems. I work in the area of Cloud Computing and WebScale in helping align Sun's initiatives in this space from partner perspective.  On this blog, I plan to discuss subjects related to the industry buzz "Cloud Computing".

Recently I attended a very interesting event called CloudCamp. As the name suggests, it was  an event where best effort was made to keep it most informal and interactive. The organisers like to call it an "Unconference", in that there is no planned agenda. The attendees meet at a venue and volunteer topics for discussion.  And Bingo, very soon an "on-the-fly" agenda is generated.

CloudCamp Unconference Agenda

Let me talk a bit about the topic "What is a Cloud?" that seemed like one of the most popular discussions of the evening. We were about 50 people in a room, analysing and disecting what CloudComputing is supposed to be, how it differentiates from Grid and Utility Computing et al. Below are several attributes of a Cloud that were thrown out:

Cloud Computing is:

1. A virtualized environment that can elastically scale up and down on demand

2. Instant easy access to aggregation of resources

3. Common Interface (API) hypervisor

4. Outsourcing of Data, compute and infrastructure

5. Enables Peak Demand

6. Grid is a multi-tenant environment where nodes are shared between applications. Cloud is a multi-tenant environment as well but users get a dedicated virtualised private set of nodes.

7. Results in Cloud vendor specific API lockin

8. Many startups to emerge to help seemless migration of apps from one cloud to another

9. Likely be specialized clouds

10. No commitment, pay for it with a Credit Card on use basis.

11. Its yet another name for Utility Computing

12. 90% of the applications being deployed in the cloud are Web 2.0 apps, rest are enterprise

13. Most large enterprise IT deployments in future would be hybrid, partly private, partly in the cloud.

Punch line was: We need to get a lot more cloudy before we are cloudy enough. :-) 

There were some other interesting sessions like:

  1. Cloud Storage
  2. Hadoop in Cloud
  3. Testing with Cloud
  4. Google App Engine
  5. Database engineering for Clouds
  6. Real performance numbers from EC2 and GoogeApps.
