Public cloud continues to grow in popularity and top providers, such as Amazon Web Services, Microsoft Azure and Google, offer competitive prices to attract enterprises. But your search to save money shouldn't stop there. There are many factors -- some of which IT teams initially overlook -- that can increase a public cloud bill. Fortunately, organizations can avoid any unwanted billing surprises with a cloud cost management strategy.
Take a hard look at your applications and review their requirements before you move them to the public cloud. In some cases, the cost of certain cloud resources can exceed what you already spend on premises. If the application is a good fit for cloud, use management and monitoring tools to identify and remove unused resources or to determine if an instance needs to be resized. If you have a multicloud model, watch out for integration costs.
This guide will take you through these best practices, and more, to build an efficient cloud cost management strategy.
1Look before you leap-
Evaluate cloud costs before migration
Before a migration, it is important to evaluate how much the public cloud will cost. Like any IT service, the public cloud can introduce unexpected charges, and some applications are better off staying in the data center. The first step of a cloud cost management strategy is to look at the public cloud providers' billing models. Take note of how much storage, CPU and memory your applications require, and which cloud instances would meet those requirements. Then, estimate how much those applications will cost in the cloud. Compare your estimates to how much it currently costs to run those apps on premises. Some workloads are more cost-effective when in house due to data location and other factors.
Some apps, such as those tightly tied to an enterprise database, may break the bank in public cloud. Before you move an app from on premises to cloud, re-examine its requirements and see where you will get the most value. Continue Reading
Not all apps are built for cloud and a redesign can cost a pretty penny. Keep an eye out for apps with strict security requirements, or those that might be bogged down by latency issues, before you make your move. Continue Reading
2Watch your wallet-
Manage and monitor public cloud computing costs
Once you're in the public cloud, you have to keep an eye on your resources. Top cloud providers offer native cloud cost management and monitoring tools, but there are also third-party options that are more specialized. Without these tools, enterprises could spend a lot of money on unused cloud resources. Form a cloud cost management strategy to look out for money pits such as cloud sprawl, overprovisioning and wrong instance types. Best practices to remedy these issues include efficient resource management and rightsizing. Take it a step further with cost optimization techniques to get the most value from the cloud.
Providers' regions and availability zones can impact how much you pay in the cloud. Look at the design of your application and where your users are to determine which region or zone to choose. Continue Reading
Major cloud providers offer tools to estimate costs, but enterprises should expect the unexpected. To form a more accurate estimate, factor in the possibilities of an outage, usage spikes and forgotten services. Continue Reading
3Multicloud cost considerations-
Prepare for multicloud costs
When using multiple public cloud providers, integration and other factors can lead to unexpected fees. Think ahead and plan application deployments to see where you might incur additional costs. Also, look at your cloud bill and see what you are charged for access, CPU and storage. The ability to track spending across more than one cloud is invaluable; incorporate providers' native billing tools into your multicloud cost management strategy, but remember that third-party tools offer more cross-platform capabilities.
Multicloud provides numerous benefits, but is can come at a cost -- especially when it comes to integration. Follow this process to minimize the costs of application integration across multiple platforms. Continue Reading
Whether you have multiple cloud deployments with one vendor or several vendors, it is hard to keep track of costs. Use provider services and third-party tools, such as RightScale, Cloudability and Cloudyn, to stay in the know. Continue Reading
