Cloud computing is ubiquitous – directly or indirectly, enterprise organizations, governments and consumers have been actively using or engaging with hosted application platforms for some time and will continue to do so for many years to come.  Lately we have been bombarded by cloud conversations, market analysis on whether cloud is greener, more secure, more cost effective or if it’s here to stay. The din of these conversations sometimes dulls out the reality that cloud is simply a necessary and expected evolution of the way we consume, access, and deliver information over the network. Click here to learn how some private sector organizations are already realizing the benefits of cloud.

With the proliferation of mobile devices, applications and social networks, consumers’ behaviors are changing and access to information anytime, anywhere and over any platform has become a norm. As devices become more relevant, more intelligent and more embedded into our day-to-day lives, we begin to expect that same seamless connected experience across the services we receive from our cities, governments, schools, etc.  Cloud enables these connected devices to go beyond the limitations of our 1:1 interactions and extends our access to services and information. With cloud computing, governments and industries can deploy more dynamic services to grow cities, deliver faster, more reliable services to citizens, and ensure greater access to a global market of opportunities and experiences.

Cloud is really about economies of scale.  Tangible upfront cost savings are difficult to measure, but if you look at cloud as a means to achieving organizational agility through efficient virtualization processes, then the savings are more quantifiable. Cloud computing won’t solve all our IT problems, but it gives us an opportunity to look beyond a siloed approach to IT and information sharing and experience the next generation of collaboration that is dynamic and reliable enough to evolve the way we currently deliver services and operate.

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.

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.

Last week I had the opportunity to attend the Citrix Synergy conference in San Francisco.   The conference was buzzing with the latest innovations for desktop virtualization, data center and cloud.   

Secure desktop virtualization infrastructure is compelling for government agencies seeking strategies to reduce costs, improve operational efficiency, and provide control and security of centralized desktops and mobile multi-media clients.

Two years ago Cisco entered the server market with the introduction of the Unified Computing System.  Our competitors met the move with skepticism, blank stares and questions around Cisco’s market strategy.  Our customers wondered what a networking company new about computing.  We didn’t let the naysayers or the doubters distract us.  We continued the hard work of innovation and communicating the architectural superiority of the Unified Computing System.  Soon customers and competitors began to take notice.
