Are Sunny Days Possible in the Cloud?

Yes, but only if there is Trust…

Do you remember not too long ago hopping into your car, driving, across town (when gas was $1- something) to your local retail store and searching the computer department to purchase a cereal box that contained between 2- 8 3.5” (or are you “wise” enough to remember 5.25” floppy) disks?  The disk contained software that would entertain us, make us more productive and educate.  If you don’t remember that, how about going to the record store and perusing the aisles for hours reading the CD boxes that were twice as big as the CD.

Well those days seem long past; and inserting a disk in anything these days….well, seems a bit ancient.

Cloud

We’re now spoiled with the conveniences of iTunes, Salesforce.com, Facebook, Youtube, Yahoo Mail, etc..  In addition, we’re all too familiar with the seemingly millions of applications that run on a myriad of mobile appliances.  None of these programs run on our PC’s hard drive.  They’re browser based applications that are essentially utility services which we share with thousands of users.

So, I began to ponder the question, “What’s the big deal about the Cloud in Manufacturing and Enterprise?”  Read More »

Conversations about Cloud – “What is Self-Service IT?”

Every once in a while (here, here), I have the same conversation enough times with customers that I find it useful to bring it to the blog community. Last week at VMworld 2011, I had the opportunity to spend quite a bit of time speaking with customers and partners about Intelligent Automation and what it means for IT to deliver self-service capabilities to their customers (internal, contractors, etc.). During the conversations, a number of questions came up over and over again: Read More »

Talkin’ Tech: Cloud Computing

Defining key terms for understanding the basics of this emerging technology

Cloud computing continues to be a hot trend in technology and is a great option for budget-minded and resource-constrained small businesses. Cloud-based services offer a more cost-effective solution for accessing applications and hardware on demand and provide small businesses with greater flexibility. In fact, many smaller companies are using cloud services without realizing it. And therein lies the challenge—there’s a general lack of understanding when it comes to cloud computing.

In this installment of our Talkin’ Tech series, we define key terms to help you understand the basics of cloud computing. If there’s a term we didn’t include that you’d like defined, please let us know!

The Role of Layer 4-7 Services in Scaling Applications for the Cloud-Computing Data Center

The Cloud Challenge
Cloud computing is increasing demands on applications and the application-delivery infrastructure must change to meet the challenge. Virtualization does not solve the problems with applications scaling, in fact it adds complexity. Infrastructure alone does not solve the challenge either. You don’t want to oversubscribe or just add capacity on demand. The infrastructure needs to respond to user demand based on business value and maintain a favorable cost structure. This means that you need intelligent load processing to manage scale, especially given the evolution of applications, which now make numerous backend function calls, which create more traffic than at the front end.

The Need for Scale
Cloud-computing applications are characterized by stateful access, with differentiated service levels, charged to the end user using the pay-per-use pricing model. Implicit in this model is the assumption that a cloud application is always on. Scaling the cloud delivery model to an Internet scale (millions of users) is a challenge that next-generation Layer 4–7 infrastructure needs to overcome.

Scaling a cloud application involves scaling three mechanisms: location (mobility), replication, and load balancing. Virtualization was an early catalyst for cloud computing because it substantially lowered the cost of replication and mobility of a prepackaged application. It does not, however, solve the load-balancing problem. Load balancing involves scaling the address, name space, transport, session, identity, and business logic of the application. Clustering enables scaling of application business logic but leaves the rest of the problem to a proxy infrastructure.

Platform as a Service: The Next Big Opportunity for Communications Service Providers

The Route to PaaS

When cloud computing emerged a few years ago Communications Service Providers (CSPs) saw the opportunity to build the infrastructure layer and offer services on it. CSPs had data center facilities that when combined with their network assets created a cloud service offer with higher service delivery assurance than some alternatives. CSPs are now delivering infrastructure-based cloud services, especially Compute as a Service and Storage as a Service, to the public and to their large Enterprise customers in private cloud offers. As the cloud service model matures, providers who have invested in cloud infrastructure are finding that they are well positioned to evolve their Infrastructure as a Service (IaaS) offerings into new service delivery models by leverage their services, systems, and expertise to take on the next great opportunity in cloud services which is Platform as a Service.

The Value of PaaS

PaaS is an integral component to development and delivery of cloud-based applications delivered as Software as a Service—or SaaS. Developing a PaaS offer gives CSPs the opportunity to take advantage of the huge and growing SaaS market and help to accelerate the development of SaaS offers. CSP’s can take an active role by leveraging their assets and developing their capabilities, via a PaaS offer, rather than just hosting and transporting SaaS services. The capability they can provide is to enable development and then deploy applications that are created using tools that they support on to their cloud infrastructure. PaaS enables CSPs to carve out a new and essential role in SaaS development and delivery, situated between software developers and end users, for both business and consumers.
