• Cloud technology allows for easy access to data from anywhere with an internet connection

• It reduces the need for physical storage devices and on-premise servers

• Examples of cloud technology include Amazon Web Services, Microsoft Azure, and Google Cloud Platform

Scaling up an instance involves increasing its capacity to handle more traffic or workload.

• Increase the instance size by adding more resources such as CPU, memory, and storage

• Use load balancing to distribute traffic across multiple instances

• Implement auto-scaling to automatically adjust the number of instances based on traffic demand

Cloud infrastructure can be recreated using other resources and configuration files.

• Terraform state file is used to track the current state of infrastructure.

• If lost, the infrastructure can be recreated using other resources and configuration files.

• However, any changes made after the state file was lost will not be reflected.

• It is important to regularly backup the state file to avoid such situations.

Cloud full form is 'Clustered Load- Balanced and On-Demand Computing'.

• Cloud is a network of remote servers that store, manage, and process data.

• It allows users to access data and applications from anywhere with an internet connection.

• Examples of cloud services include Amazon Web Services, Microsoft Azure, and Google Cloud Platform.

Load balancing in Kubernetes is achieved using a service called Kubernetes Service.

• Create a Kubernetes Service object with a type of 'LoadBalancer'

• The Service will automatically create an external load balancer that will distribute traffic to the pods in the service

• The load balancer will route traffic based on the service's selector

A storage bucket in Orchestrator is a container used to store files and data related to automation processes.

• Storage buckets can be used to store input files, output files, logs, and other data needed for automation processes.

• They help in organizing and managing data efficiently within Orchestrator.

• Examples of storage buckets include 'InputFiles', 'OutputFiles', 'Logs', etc.

Route53 is a DNS web service provided by AWS that routes internet traffic to the appropriate resources.

• Route53 is used for domain registration, DNS routing, and health checking of resources

• It can be used to route traffic to EC2 instances, S3 buckets, and load balancers

• Route53 also supports routing policies such as weighted, latency-based, and geolocation-based routing

I have set up a scalable cloud infrastructure using AWS for application deployment.

• Utilized AWS services such as EC2, S3, RDS, and Elastic Beanstalk for hosting and managing the application

• Implemented auto-scaling and load balancing to ensure high availability and performance

• Configured security groups, IAM roles, and VPC settings to secure the infrastructure

• Used CloudFormation templates for infrastructure as code to automate deployment processes

Cloud cache is a distributed caching system that stores frequently accessed data in the cloud.

• Cloud cache improves application performance by reducing the number of requests to the database.

• It can be used to store session data, user preferences, and other frequently accessed data.

• Examples of cloud cache services include Amazon ElastiCache, Microsoft Azure Cache, and Google Cloud Memorystore.

There are multiple vendors available for Credit Manager LAP.

• There are several vendors in the market that offer Credit Manager LAP services.

• The number of vendors may vary depending on the specific location and market.

• Some well-known vendors in this field include ABC Company, XYZ Corporation, and DEF Solutions.

• It is recommended to research and compare different vendors to find the one that best suits your needs.

ETL on cloud can be setup using AWS Glue or third-party tools like Talend, Matillion, etc.

• Choose a cloud-based ETL tool based on your requirements

• Create a data pipeline to extract data from source systems

• Transform the data using the ETL tool's built-in functions or custom scripts

• Load the transformed data into a target data store like S3, Redshift, etc.

• Schedule the ETL jobs to run at regular intervals

• Monitor the ETL jobs for errors and performance issues
