Happy 4th of July! We’re just getting back from Cisco Live!, and had a great time. You can check out a few posts from the show on Padmasree Warrior’s keynote, new TCL scripts in Cisco IOS, and provisioning segmented multi-tenant cloud services with service orchestration.
If you’re still confused about cloud computing, check out this post on Network World that provides the key concepts of cloud computing. The Vancouver Sun also shares some basic tenants of Platform as a Service (SaaS), Infrastructure as a Service (IaaS) and perhaps the most familiar, Software as a Service (SaaS).
Advantages and disadvantages of private cloud are examined in CIO News from TechTarget. Three main pitfalls to avoid are outlined, including expecting speed and agility, waiting to get in the game, and failing to understand self-service (from the end user and cloud administrator) and true production needs. Need more persuasion toward private cloud? According to the article, “once private clouds are up and running, they are paying for themselves in one to two quarters. An estimated one in 10 enterprise servers are sitting idle; private clouds enable them to move from less than 10% server utilization to 70%.”
A new personal blog from VMware developer Steve Jin points us to system provisioning in cloud computing, a two part post. OS, middleware, and application tools for provisioning are discussed. Steve says that in a cloud application architecture, “you want to design your applications to be as stateless as possible so that you can standardize the application for massive deployment.” He provides some examples of application provisioning tools, and summarizes saying, “System provisioning in cloud computing is an important aspect of system architecture, application design and operation, the standardized templates provide not only operational efficiency but also high quality, pre-qualified software stacks for building cloud applications.”
Although cloud computing could save the government millions of dollars, 22 out of 24 major agency executives are still worried about security, according to a GAO report. But, it appears there are more benefits than risks, at least according to Mike Bradshaw, director of Google Federal:
Despite the concerns, cloud computing will improve security. Federal. Cloud computing vendors store data on multiple servers in multiple locations, making it difficult for cybercriminals to target one location. The redundancy also means agencies are protected against disasters. The cloud enhances security by enabling data to be stored centrally with continuous and automated network analysis and protection.
While some IT system and network administrators may worry that the cloud will put them out of the job, GovinfoSecurity says otherwise. When it comes to IT security professionals need to be prepared for the cloud and for changes in how IT operations management is managed. Practitioners should focus on how the technology enables the delivery of new and unique business capability. Think about a hierarchical list of applications, environments and/or infrastructure that could be replaced by commodity cloud services, and work with management to understand how IT services can be tied together to business processes.Tagged with: automated network, cloud computing, government cloud, Government IT, IaaS, PaaS, provisioning, SaaS, security, server virtualization, VMware
