Successful Cloud Capacity Planning in 5 Steps


With every passing day, there is continuous advancement in cloud migrations by companies. The data capacity of the cloud is not the only concern for cloud migration but also the compute capacity and processing capacity. Lack of cloud capacity planning may drive to over-provisioning of the resources, which will eventually leads to resource wasting and overspending. The difficulty here is calculating the capacity requirements of your infrastructure, while still profiting from the cloud. Capacity planning for enterprises in the cloud is a vital task for optimal usage of cloud resources and decreasing the cloud cost.

With the appropriate cloud capacity planning, companies become adaptable in fostering new architectures and development to deploy applications in the cloud. Else you lose the advantages of resilient provisioning and end up paying the premium cost. The true cloud capacity planning depends on the application that is currently hosted on the server. While the application load and the load distribution keeps varying, the cloud instance must keep up and handle the traffic without inducing downtime. To handle the sudden spike in traffic, cloud solution architects are left with two scaling options, vertical scaling, and horizontal scaling. Both have benefits and drawbacks.

While vertical scaling lets the instance to be rebooted, servers will undergo a small downtime leaving the users unsatisfied. The horizontal scaling guarantees high availability and zero downtime. But, scaling doesn’t continuously promise to fulfill the right size of capacity in the cloud.  Choosing the right cloud provider with the necessary capacity instance also plays an important role in sustaining the right size of the cloud instance.

Cloud Capacity Planning can be accomplished by following the below steps :

1. Use Short-Term Instances

While provisioning an instance for longer-term meets the computing requirement, it leads to wastage of resources. It is always recommended to use the short term instance for your short-term project. Cloud Providers auctions the unused instance in the market and the customer has to bid on it with the right amount to acquire it. Such short term instance should be used for short time projects since the instance will be terminated once the bid price of instance goes higher.

For example, Amazon Web Services gives you an opportunity of spot instances. The spot instances can be started at a price far less than the on-demand instance. This enables the users to access resources for a shorter time-frame at a decreased price.

2. Use Cloud Billing Tool

Having in mind that the instance should neither be over-provisioned nor be under-provisioned. Cloud billing tool helps to determine the appropriate type of instance needed for your computing needs. The right instance class should be preferred such that it optimally utilizes the resources and still conserves cost. A good cloud billing tool will help in deciding the right instance class both in terms of size and cost.

3. Never Presume about the Cloud Spending

One important thing to note is to never presume about cloud spending. Cloud providers always specify the cost of each service in detail by giving examples. Evaluation of each workload should be completed before meeting the requirements of CPU, storage, network, memory requirements and, bandwidth. The instance of suitable size, capacity, storage, network, etc must be chosen with proper testing and optimization. Perform cost estimation to maintain the right cloud capacity to cut down further cloud expenses.

4. Right Workload Size Ensures Right Cloud Capacity

The cloud capacity planning strategies must be done to ensure the right workload size for your application is served. Before setting up the cloud infrastructure, appropriate data must be gathered. The CPU usage, storage needs, memory metrics,  and server configurations must also be documented.

Although several precautions are taken to get the cloud infrastructure size right, it is possible that your cloud infrastructure is still not accurately sized. However, this can be resolved by recording the usage parameters of all instances. Cloud Analytic tools provided by Interpole will provide such data in the simple dashboard making it easy to read the data, helps to spot the issues, and make decisions with ease.

5. Ensuring Cloud Resiliency while Migrating Applications

Before migrating to any of the cloud providers, always make sure your applications hosted in on-premises will support the cloud’s high availability and resiliency. This step is essential to avoid the extra expenses in the redesign of applications and maintaining the right cloud capacity.
