Increase Cloud Success: Calculate and Monitor the Payoff
Cloud Migration Results Not Always Better
Cloud migration is a top priority for IT leaders. After all, it promises cost reductions, to deliver just the right level of technology resources at the right time to meet a company’s needs, dilutes the risk of disaster, and enables access to applications anytime, anywhere.
While it sounds good, the rationale for cloud migration is foggier than it first appears. For example, some enterprise-sized companies do not realize cost savings because they have already created their own economies of scale. Also, high-performance requirements can significantly increase cloud costs.
Because of its ability to monitor and measure data center performance in on-premise, cloud and hybrid environments, Galileo Performance Explorer®, a cloud-based infrastructure performance management solution, is an essential tool for planning and managing a flawless cloud migration process.
Galileo’s Step by Step Approach to Cloud Migration
Follow this simplified methodology to ensure a successful cloud migration.
Monitor Your IT Infrastructure
Before moving to the cloud, monitor your IT infrastructure with Galileo to gather the historical data you need for your analysis. Ideally, you’ll want a year or more of data so you can see the peaks and valleys in demand and identify trends, but even a 30-day snapshot can help clarify your plans.
Virtually Group Test Environments
Use Galileo’s Tag Manager to group and create a profile of the applications you want to move to the cloud including utilization, CPU capacity, I/O performance and more.
Learn about Tag Manager
The profile created by Galileo is your shopping list for talking with potential cloud service providers. Rather than shopping based on an assumption that you use 100 percent of your current technology assets, this list allows you to shop for precisely what you need.
When checking out vendors, make sure you understand exactly what each vendor is offering so you can make apples-to-apples comparisons. For instance, check whether there is a performance guarantee and what it includes.
Try It Out
Most cloud service providers offer a short-term free trial. So use your disaster recovery plan to duplicate your application group and place them in each of the cloud providers’ environments.
Because Galileo is vendor-agnostic and cloud-based, you can use it to monitor each of the trials. By doing so, you can feel confident in the consistency of your comparisons of CPU, network, and disk I/O performance at each vendor. You’ll be able to surface the issues that tend not to reveal themselves in your initial conversations with cloud-service providers.
Weigh the Costs and Benefits
With insights from Galileo, you have the information you need to make educated decisions about whether your organization will benefit from cloud migration, and if so, which vendor(s) will serve you best.
Migrate to the Cloud
Once you decide that clouds are in your future and select your preferred vendors, it is time to implement the migration. When doing so, it’s best to choose a couple of cloud service providers so you don’t have your all your eggs in one basket.
It’s essential to continue to monitor the cloud environment with Galileo because:
- Cloud vendor performance can deteriorate over time, especially if they are growing and adding new customers
- If your service level agreement (SLA) guarantees a specific level of performance, you want to get what you’re paying for
- Continued monitoring provides the data you need to make decisions at the end of the contract on whether to stay with a vendor or move to another
Following this step-by-step process helps ensure cloud success or may stop you from making a move that will not be beneficial.
