1. Automated Discovery Tools
Automated discovery tools help analyze your computer programs for moving to AWS. These tools gather information about your current setup and programs.
Discovery and Initial Planning
AWS Application Discovery Service (ADS) is a tool that helps big companies plan their move to AWS. It does this by:
- Collecting data about your current computers and programs
- Storing this data safely
- Letting you download the data as a file
ADS works in two ways:
- Without installing anything extra (agentless)
- By installing a small program on your computers (agent-based)
Application Assessment Techniques
ADS helps you understand:
- How your programs work together
- What each program needs to run
It works with other AWS tools to help you keep track of your move to the cloud.
Tool Features and Capabilities
| Feature | Description |
|---|---|
| Data Collection | Gathers information about your current setup |
| Cost Estimation | Helps figure out how much running on AWS might cost |
| Migration Planning | Assists in planning your move to AWS |
| Portfolio Analysis | Looks at all your programs to see which ones are ready for AWS |
Other tools like AWS Migration Evaluator can also help with these tasks.
2. Manual Inventory Processes
Manual inventory processes involve a hands-on approach to checking if applications are ready to move to AWS. This method requires a good understanding of your applications and involves gathering data by hand.
Discovery and Initial Planning
In a manual inventory process, you need to collect information about your current setup and applications. This includes:
- Details about the applications
- How applications depend on each other
- The computers and systems the applications run on
You can gather this information by:
- Talking to the people who own or manage the applications
- Looking at existing documents
- Checking system records
Application Assessment Techniques
After collecting the data, you need to look at it closely to understand:
- How applications work together
- What each application needs to run
- Which applications depend on others
This helps you spot possible problems that might come up when moving to AWS and helps plan the move.
Portfolio Rationalization Strategies
When doing a manual inventory, you also need to decide which applications should move to AWS. This involves looking at:
| Aspect | What to Consider |
|---|---|
| Business Value | How important is the application for the company? |
| Technical Fit | Can the application work well on AWS? |
| Benefits | What good things could happen by moving to AWS? |
3. Hybrid Approaches
Discovery and Initial Planning
Hybrid approaches mix automatic tools and manual checks. This method uses tools to gather data, then people review and improve the results. This can make the data more accurate and save time compared to doing everything by hand.
For example, you can use AWS Application Discovery Service (ADS) to automatically collect information about your current setup. Then, people can check this information to make sure it's correct. This helps find possible problems that the tools might miss.
Tool Features and Capabilities
Hybrid approaches use different tools to help with discovery and planning. Here's a table showing some tools and what they do:
| Tool | What it Does |
|---|---|
| AWS Application Discovery Service (ADS) | Automatically finds applications and how they connect |
| AWS Migration Evaluator | Gathers data about your current setup and applications |
These tools can help you:
- Find possible problems
- See how applications depend on each other
- Guess how much AWS might cost
- Try out different ways to move to AWS
