Now that you've decided on a hybrid cloud solution, you need to determine the necessary capacity and usage. Transitioning to any new IT infrastructure requires very careful planning, and capacity planning is an important part of this. You will need to review your organization's present usage in addition to projecting out the resources that you will need in the future.
Review Your Current Usage
Determining your capacity needs begins with reviewing your current usage. You will need data regarding your peak traffic and resource needs in addition to your average requirements. Ideally your system will need to compensate for increased load while still avoiding the maintenance and cost of unnecessary resources. One of the best things about cloud technology is that it is both elastic and scalable, but you still need to have a reliable starting point.
Study Your Applications
In a hybrid solution, one of your first determining factors will be which applications are going to live on-premise and which applications are going to live on the cloud. This can be a complex issue; you need to determine which applications are best suited to a cloud environment and which applications will not gain anything from the transition. Applications that need low latency and heightened security, such as your backups, are often better on an on-premise server, whereas applications that need accessibility and scalability are generally better on a cloud solution.
Building Analytic Models
You will need to project out how much your network needs will grow in the future. This can be done through the analysis of your past growth. Build out models that show how your network is presently growing. You need to be able to give yourself enough room to scale in the near future. You should also consider any future plans for growth; your analytical models may not otherwise be accurate predictors of the future.
Simulate Your Deployment
Though it may be a somewhat time consuming process, it's still important to simulate deployments before committing to them. Run rigorous tests regarding not only the average loads but also peak traffic, to ensure that the system operates correctly and that business interruption doesn't occur. Your analysis will need some buffer to also compensate for any unanticipated loads, and you will need to analyze both sides of your hybrid solution in addition to how well they work together.
