Types of Salesforce environments

Types of Salesforce environments:

     Developer environment:

• The environment where we have access to all the tools to build our application and test it.
• It has a limited space and cannot be used as a production environment.
• It is a free edition.

    Production environment:

• Production environment needs a license purchased from Salesforce to get access to production and sandbox environments.
• End users use the production environment.

    Sandbox environment:

•  Sandbox gives the ability to create multiple copies of the organisation in separate environments for different purposes such as development,training,testing and deployment.
• When we create a sandbox,Salesforce automatically copies the metadata from production to sandbox for development and when the development is complete,the metadata is copied to another sandbox for quality assurance and finally moved to production.

Types of Sandbox environments:

      Developer :

• Used for coding and testing.
• It copies the metadata.

      Developer pro:

• Used for coding and testing 
• It has a larger storage limit.
• It copies the metadata

     Partial copy:

• This is mostly used as testing environment,quality assurance such as integration testing and training.
• It can have metadata and a sample object data. 

     Full copy:

• Used as testing environment.
• It can support full performance testing and load testing.
• It is an exact replica of production environment including all data.
• It has entire metadata and data.
