Given all the talk about virtualization and cloud computing these days, and the number of vendors promoting related products, it should come as no surprise that enterprise companies are rapidly migrating applications to virtual and cloud environments. A recent survey of IT managers in North America, conducted by Precise, revealed that 41 percent of companies have migrated sales and marketing, HR, finance and/or ERP applications to the cloud this year. Participants told us that they would continue their aggressive push to the cloud next year.
Here are a few highlights:
• In 2011, 39% of organizations moved email and collaboration systems to virtual infrastructure, followed by IT management (33%) sales & marketing (20%) finance/HR/ERP (21%) and security (13%).
• In 2012, 33% of respondents report that they will move finance/ERP /HR applications to the cloud, followed by e-mail and collaboration software (23%) and IT management applications (21%).
Given the public perception that security and reliability are weaker in the public cloud, enterprises are favoring private clouds today and in the near future, according to our survey. Eventually, 37% of companies say they will migrate 61% or more of their applications to a private cloud environment, while only 6% of companies will do the same on a public cloud service.
This is all positive news. In a volatile global economy, virtualization and cloud computing offers enhanced agility, scalability and efficiencies for companies needing to do more with less. As the virtualization and cloud industry has matured, there are now many flavors and service providers to choose from, as dictated by your unique needs and budget. Many companies expect that after migrating, they will have more flexibility to meet business objectives and will also save money on capital investments and staff. These are valid expectations, which have already proven out in companies large and small in the past few years.
It's not all rosy, of course. The cloud is still a new infrastructure, one which is much more dynamic and flexible compared with older, static networks, physical servers and rigid legacy applications. The cloud can create more complexity and risk if an organization is unprepared to manage security, reliability, and transaction performance through the various physical and virtual layers. Because of the nature of dynamic provisioning in the cloud and server cluster architecture, it's difficult to determine which server, VM, or application instance is to blame when troubleshooting issues.
Another potential pitfall is that the shared-resource model of the cloud can become a double-edged sword. The cloud architecture can save costs through optimization of resources, yet it also increases the chances of resource contention by orders of magnitude. Your slow application may be a result of someone else's app residing on the same server or sharing the same storage pool.
The survey found that IT's number-one virtualization concern is maintaining performance and being able to effectively troubleshoot problems. After slow performance (41%), the second leading problem of managing applications in the cloud is slow time to identify the root cause of issues. This is a tough balancing act for the CIO, who needs to deliver IT agility for the business, yet at the same time deliver adequate protection for data and applications. IT service delivery folks are increasingly looking at products and services that will help run critical applications in production. It's kind of like buying insurance -- you really need it when you’re talking about high-priority business applications.
Application management technology must step up for cloud computing. It needs to see through all the virtual layers where there is constant change from moving VMs and contention on resources. The only answer is automation -- at a much grander and faster pace than in the past. It is the win-win-win for CIOs: agile provisioning, lower cost, and reliable applications.
