Cloud Cloud Computing Overview and AWS Introduction Notes Security and Database Services AWS provides robust flexible and secure cloud based database services These services include Amazon RDS Amazon DynamoDB and Amazon Redshift AWS also offers Amazon Document DB a document database service that supports MongoDB workloads AWS provides a variety of security measures such as network firewalls web application firewall encryption in transit and at rest and access control mechanisms AWS Professional Services Framework The AWS Professional Services Framework provides a systematic approach to helping customers successfully implement cloud solutions It focuses on defining the engagement structure establishing the governance model and identifying the skill sets required The framework consists of three phases 1 Discovery 2 Planning 3 Migration EC2 Service Creation Benefits Amazon EC2 Elastic Compute Cloud is a web service that provides resizable and secure compute capacity in the cloud Benefits of using EC2 include Faster time to market 2 Reduced capital costs 3 Improved security and compliance 4 Increased scalability and flexibility Ability to quickly add or remove capacity based on workload requirements Role of a Devops Engineer A devops engineer is responsible for managing and optimizing the development and deployment of software in a cloud environment Key responsibilities include Designing and implementing automation solutions Managing infrastructure as code Ensuring efficient collaboration between development and Ensuring reliability scalability and security of cloud based operations teams applications Storage Engineering and Maintenance AWS provides a range of storage services for different use cases such as Amazon S3 Amazon EBS Amazon EFS and Amazon FSx AWS Storage services provide high durability reliability and security Amazon S3 object storage for backup archive and analytics Amazon EBS Amazon EFS Amazon FSX block storage for use with EC2 instances elastic file storage for use with EC2 instances fully managed file systems for use with Windows and Linux workloads Storage engineering and maintenance responsibilities include creating managing monitoring and optimizing storage infrastructure service sources Cost and Refund Management AWS provides a cost effective and flexible pricing model that allows customers to pay for only the services they use AWS also offers cost optimization services such as AWS Cost Explorer AWS Budgets and AWS Cost and Usage Reports AWS provides a refund policy for certain cases such as billing errors fraudulent activity or misuse of services It s important to monitor and manage the usage and costs of AWS services to ensure that you re not overspending or wasting resources EC2 Service Creation and Benefits Security AWS provides robust security features for EC2 instances including Amazon provided firewall configurations and the ability to enable disable instances for added protection Encryption of data at rest and in transit is also supported along with the ability to create custom security policies Database Services AWS provides a variety of database services that can be integrated with EC2 instances such as Amazon RDS Amazon DynamoDB and Amazon Redshift These services offer easy setup and management of databases as well as automatic backups and scaling AWS Professional Services Framework The AWS Professional Services Framework offers a set of best practices and methodologies for deploying and managing applications on AWS This framework can be used to ensure secure and efficient deployment of EC2 instances
