A – Aurora
Amazon Aurora is a fully managed MySQL-compatible relational database engine that combines the speed and availability of commercial databases with the simplicity and cost-effectiveness of open-source databases.
B – Bucket
A bucket is a container for objects. To store your data in Amazon S3, you first create a bucket and specify a bucket name and AWS Region. Then, you upload your data to that bucket as objects in Amazon S3. Each object has a key (or key name), which is the unique identifier for the object within the bucket
C – CI/CD
CI and CD stand for continuous integration and continuous delivery/continuous deployment. CI is a modern software development practice in which incremental code changes are made frequently and reliably. Automated build-and-test steps triggered by CI ensure that code changes being merged into the repository are reliable. The code is then delivered quickly and seamlessly as a part of the CD process. In the software world, the CI/CD pipeline refers to the automation that enables incremental code changes from developers’ desktops to be delivered quickly and reliably to production.
D – DynamoDB
Amazon DynamoDB Streams is an AWS service that captures a time-ordered sequence of item-level modifications in any Amazon DynamoDB table. This service also stores this information in a log for up to 24 hours. Applications can access this log and view the data items as they appeared before and after they were modified, in near-real time
E – Elastic Compute Cloud (EC2)
Amazon Elastic Compute Cloud (Amazon EC2) is a web-based service that allows businesses to run application programs in the Amazon Web Services ( AWS ) public cloud. Amazon EC2 allows a developer to spin up virtual machines (VMs), which provide compute capacity for IT projects and cloud workloads that run with global AWS data centers.
F – FinOps
FinOps is an evolving cloud financial management discipline and cultural practice that enables organizations to get maximum business value by helping engineering, finance, technology, and business teams to collaborate on data-driven spending decisions
G – Gateway
A cloud storage gateway is a hardware- or software-based appliance located on the customer premises that serves as a bridge between local applications and remote cloud-based storage.
H – Heroku
Heroku is based on AWS. It supports efficient building, deploying, and fast scaling. It is popular for its add-on capabilities as it supports many alerts and management tools
I – Intrusion Detection System (IDS)
An Intrusion Detection System (IDS) is a monitoring system that detects suspicious activities and generates alerts when they are detected
J – Jenkins
Jenkins is an open-source automation server. With Jenkins, organizations can accelerate the software development process by automating it. Jenkins manages and controls software delivery processes throughout the entire lifecycle, including build, document, test, package, stage, deployment, static code analysis, and much more.
K – Kubernetes
Kubernetes, also known as K8s, is an open-source system for automating the deployment, scaling, and management of containerized applications. Kubernetes automates operational tasks of container management and includes built-in commands for deploying applications, rolling out changes to your applications, scaling your applications up and down to fit changing needs, monitoring your applications, and more—making it easier to manage applications
L – Lambda
AWS Lambda is a serverless, event-driven compute service that lets you run code for virtually any type of application or backend service without provisioning or managing servers. You can trigger Lambda from over 200 AWS services and software-as-a-service (SaaS) applications and only pay for what you use. Use Amazon Simple Storage Service (Amazon S3) to trigger AWS Lambda data processing in real-time after an upload, or connect to an existing Amazon EFS file system to enable massively parallel shared access for large-scale file processing.
M – Migration
Cloud migration is the process of moving digital assets — like data, workloads, IT resources, or applications — to cloud infrastructure. Cloud migration commonly refers to moving tools and data from old, legacy infrastructure or an on-premises* data center to the cloud. Though “cloud migration” typically refers to moving things from on-premises to the cloud, it can also refer to moving from one cloud to another cloud. Migration may involve moving all or just some assets. It also involves a whole lot of other things. That’s why we’ve compiled this guide to cover all things cloud migration.
N – NoSQL
NoSQL databases (aka "not only SQL") are non-tabular databases and store data differently than relational tables. NoSQL databases come in a variety of types based on their data model. The main types are document, key-value, wide-column, and graph. They provide flexible schemas and scale easily with large amounts of data and high user loads.
O – On-Premises
On-premises refers to IT infrastructure hardware and software applications that are hosted on-site. This contrasts with IT assets that are hosted by a public cloud platform or remote data center. Businesses have more control of on-premises IT assets by maintaining the performance, security, and upkeep, as well as the physical location
P – Public Cloud
Public Cloud is an IT model where on-demand computing services and infrastructure are managed by a third-party provider and shared with multiple organizations using the public Internet. Public cloud service providers may offer cloud-based services such as infrastructure as a service (IaaS), platform as a service (PaaS), or software as a service (Saas) to users for either a monthly or pay-per-use fee, eliminating the need for users to host these services on-site in their own data center.
Q – Query string authentication
An AWS feature that you can use to place the authentication information in the HTTP request query string instead of in the Authorization header, which provides URL-based access to objects in a bucket
R – Redshift
Amazon Redshift uses SQL to analyze structured and semi-structured data across data warehouses, operational databases, and data lakes using AWS-designed hardware and machine learning to deliver the best price-performance at any scale.
S – Serverless
Serverless is a cloud-native development model that allows developers to build and run applications without having to manage servers. There are still servers in serverless, but they are abstracted away from app development. Your application still runs on servers, but all the server management is done by AWS
T – Terraform
Terraform is an infrastructure as a code tool that lets you define both cloud and on-prem resources in human-readable configuration files that you can version, reuse, and share. You can then use a consistent workflow to provision and manage all of your infrastructure throughout its lifecycle. Terraform can manage low-level components like computing, storage, and networking resources, as well as high-level components like DNS entries and SaaS features
U – Utility billing
Unit testing is defined as a quality assurance technique where application code is broken down into component building blocks – along with each block or unit's associated data, usage processes, and functions – to ensure that each block works as expected.
V – Vendor
An organization that sells computing infrastructure, software as a service (SaaS), or storage. Vendor Insights helps simplify and accelerate the risk assessment and procurement process
W – WAF
A WAF or web application firewall helps protect web applications by filtering and monitoring HTTP traffic between a web application and the Internet. By deploying a WAF in front of a web application, a shield is placed between the web application and the Internet. While a proxy server protects a client machine’s identity by using an intermediary, a WAF is a type of reverse proxy, that protects the server from exposure by having clients pass through the WAF before reaching the server
X – X-Ray
AWS X-Ray is a web service that collects data about requests that your application serves. X-Ray provides tools that you can use to view, filter, and gain insights into that data to identify issues and opportunities for optimization.
Y – YAML
YAML is a digestible data serialization language often used to create configuration files with any programming language. Designed for human interaction, YAML is a strict superset of JSON, another data serialization language. But because it's a strict superset, it can do everything that JSON can and more.
Z – Zone Awareness
Zone awareness helps prevent downtime and data loss. When zone awareness is enabled, OpenSearch Service allocates the nodes and replica index shards across two or three Availability Zones in the same AWS Region. Note: For a setup of three Availability Zones, use two replicas of your index.
