Because of its ability to monitor and measure data center performance in on-premise, cloud and hybrid environments, Galileo Performance Explorer is an essential tool for planning and managing a flawless cloud migration process.
Follow this simplified, step-by-step methodology to ensure a successful cloud migration with Galileo:
1. Monitor Your IT Infrastructure
Before moving to the cloud, comprehensively monitor your entire IT infrastructure 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 if you are a expedited timeline.
2. 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 in order to view valuable metrics including utilization, CPU capacity, I/O performance and more.
3. Shop Around
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 an apples-to-apples comparison. For example, be sure to check whether there is a performance guarantee and what it includes.
4. 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 bring to light the issues that tend not to reveal themselves in your initial conversations with cloud service providers.
5. Weigh the Costs & Benefits
With insights from Galileo, you will have the information you need to make educated decisions about whether your organization will benefit from cloud migration, and if so, which vendors will serve you best.
6. 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 monitoring your cloud environment with Galileo for many reasons:
- 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.
