Problem Statement: Use boto3 library in Python to restore all secret keys from specific location in AWS Secret Manager.Approach/Algorithm to solve this problemStep 1: Import boto3 and botocore exceptions to handle exceptions.Step 2: secret_stored_location is the required parameter.Step 3: Create an AWS session using boto3 lib. Make sure region_name is mentioned in the default profile. If it is not mentioned, then explicitly pass the region_name while creating the session.Step 4: Create an AWS client for secretmanager.Step 5: Call restore_secret and pass the secret_stored_location as SecretId.Step 6: It returns the metadata of restored secret.Step 7: Handle the generic exception if something ...

In this post, we will understand the difference between RPC and RMI −RPC (Remote Procedure Call)It is a library.It is an OS dependent platform.It supports procedural programming.It is less efficient in comparison to RMI.It creates more overhead.The parameters passed to RPC is normal data.It is the older version of RMI.It is easy to program in RPC.It doesn’t provide any security.The cost of development is high.Versioning is a complicated process in RPC.Multiple codes will be needed to build a simple application in RPC.RMI (Remote Method Invocation)It is a platform based on Java.It supports object-oriented programming.It is more efficient in comparison to ...

Problem Statement: Use boto3 library in Python to create a secret key as plain text in AWS Secret ManagerApproach/Algorithm to solve this problemStep 1: Import boto3 and botocore exceptions to handle exceptions.Step 2: secret_stored_location and secret_key_pair is the required parameter. It is a place where secrets are saved with given key-pair value. Make sure secret_key_pair is written as string, not as dict. For example: '{key:pair}'Step 3: Create an AWS session using boto3 lib. Make sure region_name is mentioned in the default profile. If it is not mentioned, then explicitly pass the region_name while creating the session.Step 4: Create an AWS ... Read More

Problem Statement: Use boto3 library in Python to paginate through multi-part upload objects of a S3 bucket from AWS Glue Data Catalog that is created in your accountApproach/Algorithm to solve this problemStep 1: Import boto3 and botocore exceptions to handle exceptions.Step 2: prefix_name, max_items, page_size and starting_token is optional parameter for this function while bucket_name is required parameters.Prefix_name is the specific sub folders where user wants to paginate throughmax_items denote the total number of records to return. If the number of available records > max_items, then a NextToken will be provided in the response to resume pagination.page_size denotes the size ... Read More
