The abbreviation of AWS is amazon web services. The AWS service is provided by the amazon that uses the distributed IT infrastructure to provide different resources. AWS offers flexible, reliable, easy to use, and cost-effective solutions. It provides different types of services such as software as a service(SaaS), infrastructure as a service(IaaS), and platform as a service(PaaS).
AWS started Its services to the market in the form of web services, which is now called “cloud computing”.

Uses of AWS:
- An architecture consulting company can use AWS to get the high rendering of the construction prototype.
- A media company can use the AWS to provide different types of content such as ebox or audio files to the world wide files.
What is AWS lambda??
Lamda is used to encapsulate Data centres, hardware, Assembly code or protocols, high-level languages, operating systems AWS, etc. Lamda is a computed service where you upload your code and create the lambda function.
Upcoming Python SDK changes in AWS Lambda:
This record describes the upcoming change to the AWS SDK that provides that affects python developers using the requests module in boto-core. This post explains the why changes are happening and describe what python developers must do to continue using request library.
The upcoming changes to AWS SDK:
Botocore is the low-level interface to many services in the AWS Cloud. The package is the foundation for AWS CLI and also Boto3, which is the AWS SDK for python. In August 2018, Botocore was refactored to allow the pluggable HTTP Clients.
One of the main changes is that the request library was replaced with urillb3. Additionally, the requested dependency was also uncensored, which means botocore can supports the scope of versions of urillb3, instead of depending on specific versions. From version 1.13.0, the request module is no longer part of the AWS SDK for python. These changes create additional flexibility for python developers and can result in performance improvements for an application using Botocore.
Although the SDK has removed the requests module, the lambda services continuous to bundle the request module in the AWS SDK until march 30,2020. Hence the builder has additional time to decide on the best course of action for there python lambda functions that rely on the request module.
Best implementation for using the AWS SDK:
For benefit, the Lambda service includes the AWS SDK in its execution environment. This allows Lamda to interoperate with the growing number of AWS services and Features released to users.
The best implementation for Lamda development is the collection of all the dependencies used by your Lamda function, using the AWS SDK. By doing this your code uses the bundled version and is not affected when the version in the execution environment is upgraded. This is preferable to using the included version of the SDK, since this version can change, and in rare cases might affect suitable with your code.
If you are currently collecting the SDK version in your Lambda version, you do not need any further action. Your code Continuous to use the bundled version and the upcoming changes do not affect you.
Import the requests module directly in your code:
If you are using the AWS SDK in the Lambda execution environment and do not want to bundle a version into your zipped deployment package, you have a couple of additional options.
First, you can install the requests module into your python environment and import the module directly. Currently, You may be importing the library from your botocore in your AWS lambda function using this code.
Python
From botocore .vendored import requests
Python
First, we install the requests module, enter the following in a terminal window:
Python
pip install requests -t./
After the installation, update the import statement in your code as shown below:
Python
Import requests
This updates your dependency from the botocore vendored version to a locally packaged version of the module. As a result, your code is unaffected after the request module is no longer available via the AWS SDK in the execution environment.

Conclusion:
Botocore helps to improve flexibility and performance for the AWS SDK. If you are bundling a fixed AWS SDK version with your python version, you do not need to take any action. If you are using the AWS SDK included in the execution environment and want to continue using the request module, you can include the Lambda layer with the appropriate AWS SDK version, or include the requests module directly in your application package.
