Diffrence between SDLC and STLC

-
Software Development Life Cycle :

Software is built rather we should say that software is engineered in various phases.As soon as one phase is complete we move on to another phase or we can work with two different phases hand in hand.These phases start with from requirement gathering from client & goes till maintenance of this project.
SDLC is lifecycle of these various different phases form top to bottom.

Various part of SDLC are :

1.Planning
2. Requirement Gathering
3. Designing
4. Coding
5. Integration & Testing
6. Installation & Acceptance
7. Maintenance

Software Tetsing Life Cycle:

STLC is part(Phase) of complete software development life cycle.In this phase we ensure that the product we building is as per requirement given by client or not.This phase start from Requirement Study & ends with till the exit criteria of testing is meet.

Various part of STLC are :

1. Requirement Gathering/Study
2. Test Case Planning
3. Test Case Designing
4. Test Case Review
5. Test Bed Setup
6. Test Case Execution
7. Bug Reporting
8. Functional Testing
9. Regression Testing
10. END (Meet Exit Criteria)

Cloud Byte 2 - Common AWS Services for Cloud Practitioner Certification (CCP)

-
CloudWatch - Focuses on the activity of AWS services and resources, reporting on their health and performance. You can collect & track metrics . You can use Amazon CloudWatch Logs to monitor, store, and access your log files from Amazon Elastic Compute Cloud (Amazon EC2) instances, AWS CloudTrail, Route 53, and other sources. CloudWatch Logs enables you to centralize the logs from all of your systems, applications, and AWS services that you use, in a single, highly scalable service. You can then easily view them, search them for specific error codes or patterns, filter them based on specific fields, or archive them securely for future analysis. By default, logs are kept indefinitely and never expire. You can adjust the retention policy for each log group, keeping the indefinite retention, or choosing a retention periods between 10 years and one day. CloudTrails – Who is doing what in AWS . It is a log of all actions that have taken place inside your AWS environment. AWS Cloud...

Equivalence Class Partitioning

-
ECP is a testcase design techniques that divides the input data into set of partitions of data from which test case can be derived. The thumb rule is that there should be at least one class for each of partitions. It is expected that each member of class will have same behavior in the system. In other way ECP method creates same set of Input/Output that are handled in the same way by the application. This method helps to reduce number of test cases as we create classes for of test data & test them accordingly. The test that results from the representative value for a class is said to be "equivalent" to the other values in the same class. If no errors were found in the test of the representative value, it is reasoned that all the other "equivalent" values wouldn't identify any errors either.   For ex. lets have a systesm which takes 2 integer value & add them.As we know that sum of two integer will always be a positive Integer so if we have to test w...
