Study Notes

Jenkins

Jenkins is a tool used for continuous integration and continuous delivery (CICD)
Jenkins can be used to build, test and deploy applications
The Jenkins file can be written in declarative or scripted pipeline syntax
Jenkins can be configured to use SonarQube for static code analysis
Jenkins needs Java to be installed on the server to run
Jenkins uses the JAVA_HOME environment variable to specify the location of the Java installation
Jenkins can be used to poll Git repositories for new commits
Jenkins build triggers can be used to automatically start builds when new commits are made to a Git repository
Jenkins can be configured to trigger builds based on a cron expression
Jenkins can be used to configure build jobs to be triggered only if a previous job is successful
Jenkins can be configured to trigger other Jenkins projects after a build is completed

Python

Python uses the concept of map, filter, and reduce for data manipulation.
The map() function applies a given function to each element of an input iterable, returning an iterator with the results.
The lambda keyword creates anonymous functions in Python.
The try block is used to execute code that might raise an exception.
The except block is used to handle exceptions that might occur in the try block.
The finally block is used to execute code regardless of whether an exception is raised or not.
Python functions can have default arguments.
Python lists are mutable.
Python sets are mutable.
Python sets are unordered.
Python lists are ordered.
Python lists are mutable.
Python tuples are immutable.

AWS

EBS (Elastic Block Storage) is a storage type used for EC2 (Elastic Compute Cloud) instances.
ELB (Elastic Load Balancer) is a service used for distributing traffic to multiple EC2 instances.
Connection draining in ELB ensures that requests are completed before an instance is deregistered.
AWS offers two types of ELB: Classic Load Balancer and Application Load Balancer.
The Classic Load Balancer is used to distribute traffic to multiple instances across Availability Zones.
The Application Load Balancer is used for application-level routing and load balancing.
S3 (Simple Storage Service) is a storage service used to store objects, such as files and data.
ACL (access control list) and policies are used to manage permissions for access to S3 buckets.
AWS offers various pricing options for different storage types.
Auto Scaling is a feature used to automatically scale up or down the number of instances in an EC2 Auto Scaling group.
Auto Scaling groups can be scheduled to automatically scale up or down based on the time of day.
CloudWatch is a monitoring service that can be used to monitor EC2 instances and other services.
CloudWatch can be used to collect and analyze data from various AWS services, including EC2, S3, and DynamoDB.
IAM (Identity and Access Management) is a service used to manage users and permissions.
IAM policies can be used to control access to AWS resources.
IAM policies can be used to restrict access to specific resources based on tags.

Azure

Azure Active Directory (Azure AD) is a cloud-based identity and access management service for Azure.
Azure AD can be used to manage user accounts, groups, and permissions for access to Azure resources.
Multi-factor authentication (MFA) is a security feature that can be enabled in Azure AD.
Azure AD allows you to manage user access for common services, like Microsoft 365.
Azure AD allows you to add custom domains, like your company’s domain, to your Azure AD tenant.
You can create a conditional access policy to control the way users sign in to Azure AD.
Azure AD allows you to use a different DNS server for your domain.
Azure Availability Zones are physically separate locations within a Azure region, allowing your application to stay online in the event of an outage.
Setting up your VMs across regions protects your application in the event of an Azure datacenter outage.
Azure provides many services, including storage, compute, and networking.
Azure services are billed based on usage. You can choose a payment option based on your needs.
Azure services are available in many regions around the world.
Azure allows you to connect to a network based on your specific needs.
Azure provides a variety of tools and services for managing your cloud resources.
Azure allows you to use a variety of deployment methods to deploy resources.
An Azure resource manager template is a declarative way to define the infrastructure and configuration of your Azure resources.
Azure has many advantages, such as scalability, agility, and cost-effectiveness.
Azure provides a wide range of features and services, including storage, compute, networking, databases, security, and analytics.
Azure is a cloud computing platform that is used by many businesses and organizations around the world.
