Access to “Cloud Services” can provide effective and flexible access to key apps and services. The right strategy can reduce the capital expense of implementing and maintaining IT infrastructure. But it is not for everyone.
A private cloud maintains services and infrastructure on a private network; it is essentially an extension of an enterprise’s traditional datacentre that is optimized to provide storage capacity and processor power for a variety of functions.
A private cloud offers the greatest level of cloud security and control, but requires the purchase and maintenance of all software and infrastructure, which in many cases reduces anticipated cost savings.
A private cloud is considered feasible where: –
• Your data and your applications is your business; control and security are paramount.
• Your business is part of an industry that must comply with specific legislation or strict data security standards. Examples of these include Payment Card Industry (PCI), Sarbanes-Oxley Act (SOX), Health Insurance Portability and Accountability Act (HIPAA).
• Your company is large enough to run and maintain a next generation cloud data centre efficiently and effectively on its own.
To complicate things, the lines between private and public clouds are blurring. For example, some public cloud companies are now offering private versions of their public clouds. Some companies that only offered private cloud technologies are now offering public versions of those same capabilities.
A hybrid cloud typically includes a variety of public and private options with multiple providers. Spreading applications over a hybrid cloud, keeps each aspect of your business in the most efficient environment possible. This typically minimises costs, however this also involves having the expertise to manage multiple and often very different security platforms, whilst most importantly, ensuring that all aspects of the business can communicate effectively.
A couple of scenarios where a hybrid environment may be best suited: –
• Your company is considering the benefits of Software as a Services (SaaS) applications but is concerned about security. Your SaaS vendor can create a private cloud just for your company behind their Firewalls; however they suggest access using a Virtual Private Network (VPN) for additional security.
• Your company offers services that are tailored for different vertical markets. You can use a public cloud to interact with the clients but keep their data secured within a private cloud.
