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. Read More »
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 agenciesseeking 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. Read More »
The Unified Network Services (UNS) portfolio of Layer 4-7 services (such as ACE and WAAS) also includes Cisco’s data center security solutions. A critical part of that security portfolio is our virtualization-aware firewall solution, Virtual Security Gateway (VSG). In a series of upcoming blog posts, I’ll be sharing a few use case scenarios that our customers are implementing with VSG.
For those of you new to VSG, I’ll point out that VSG’s role is to act as a virtual firewall between zones of virtual machines. Isolating traffic between VM zones has been very challenging prior to VSG because: 1) security policies have to be enforced between VMs running on the same server or same virtual switch (where there’s no place to put a firewall), 2) VMs move all around the network and the security policies (as enforced in the firewall) must follow the VM, and 3) the need to maintain segregation of duties for compliance purposes between the security and application server teams, where security is potentially enforced inside the virtual server.
I was over in Cisco’s building 32 the other day and was about to meet with the collaboration team when I saw something that looked a lot like Facebook running on a Cius and an iPhone. As I went over to explore, I met Raghurama Bhat and Ashish Chirputkar, the two ‘humble’ engineers who created Cisco Quad, our enterprise social collaboration platform.
I started wondering how Bhat and Chirputkar had the time to develop Quad, how internal development began, and why a Facebook,Twitter or LinkedIn for the enterprise makes sense. So with my HD video camera already in hand, I recorded this interesting feature interview. These two engineers and their team had a huge impact on how work is now done at Cisco where over 70,000 employees live their days in Quad to get their work done and collaborate.
