Gap Analysis
|
|
============
|
|
|
|
Before formulating your Cloud migration strategy:
|
|
|
|
- **Review** the current accounts, special requirements, key issues and challenges of the current IT systems.
|
|
- **Identify** new possible requirements for future service evolution.
|
|
- **Define** the key cloud adoption objectives as required.
|
|
|
|
To get a complete analysis, refer to the following **Cloud Maturity Assessment Model**:

Key gap analysis tasks include:
|
|
|
|
Infrastructure analysis
|
|
***********************
|
|
|
|
- Infrastructure resources and configurations, including servers,
|
|
storage types, basic configurations, resource quantities and usages,
|
|
lifecycle configurations, virtualization technologies,
|
|
containerization, and application distribution.
|
|
|
|
- Special requirements for performance, security, or operating system
|
|
or hardware dependencies.
|
|
|
|
- Key challenges, such as low availability and complicated maintenance.
|
|
|
|
Technical platform analysis
|
|
***************************
|
|
|
|
- Basic platform details, such as the amount, scale, and usage of
|
|
middleware, database, data warehouse, big data, and development and
|
|
test platforms.
|
|
|
|
- Special requirements and key challenges. For example, middleware and
|
|
big data are developed based on open source software, which often has
|
|
weak performance, poor stability, or no DR capabilities for critical
|
|
services.
|
|
|
|
Major application analysis
|
|
**************************
|
|
|
|
Key applications need to be identified and analyzed to classify key
|
|
requirements for the implementation. This includes systems such as
|
|
channel systems, service systems, mission-critical systems, and data
|
|
related systems. Channel systems require flexible performance scaling
|
|
and fast iteration. Service systems need to be reliable and can expand
|
|
on demand. Mission-critical and data related systems require high
|
|
reliability, stability, and concurrency.
|
|
|
|
Design for X (DFX) capability analysis
|
|
**************************************
|
|
|
|
Review the challenges related to DR, security, performance, and O&M.
|
|
|
|
Evolution of innovation
|
|
***********************
|
|
|
|
New technologies such as AI, blockchain, and fast iteration based on
|
|
containers, microservices, and cloud-native can leverage the public
|
|
cloud for rapid reconstruction.
