In contast with On-Premises IT, the user will access ressources ( apps/ database/ server / storage ... ) throught the internet.
It's an on demand delivery of compute power, database, storage,.. via the internet with pay as you go pricing.
- Variable expense : only pay for what the customer consumes when they need to.
- Benefit from massive economy of scale : AWS achieves heigher economy of scale -> lower pay as you go prices.
- guessing capacity : Eliminates guessing on infrastructure capacity needs, no idle ressouce waiting, ressources in cloud computing can scale according to the demand.
- Speed and agility : New IT ressources are available within minutes.
- Stop spending money on running and maintaining infrastructure.
- Deploy globally (multiple regions) in minutes.
AWS offers a huge range of features and services to help customers achieve their goals.
AWS Global Infrastructure
-
AWS cloud computing ressources are hosted in multiple locations called AWS regions. Each region is completly isolated -> great fault tolerance and stability -> increased resiliency.
Ressources are only viewable withtin the region, no ressources are replicated automatically across regions.
How to choose a region?:
- Compliance : requirements (exmaple country requirment)
- Proximity : close to customer (speed and latency)
- Feature availability : not all features are availble in all regions.
- Pricing : not same pricing for all regions.
-
Seperated geographic area with multiple isolated locations. All AZ are interconnected with high bandwidth low latency fully redundent fiber.
A minimum of 2 AZ is available in each region.
Deploying on multiple AZ in the same region improves availability.
On Instance runs in One AZ.
-
Edge locations and regional Edge cache servers are used by Amazon CloudFront (global content delivery service) to store cached data, video, apps and APS with low latency transfer speed closer to customers. It accelerate communication and content delivery.
-
AWS Outposts is a fully managed service that offers the same AWS infrastructure, AWS services, APIs, and tools to virtually any datacenter, co-location space, or on-premises facility for a truly consistent hybrid experience. AWS Outposts is ideal for workloads that require low latency access to on-premises systems, local data processing, data residency, and migration of applications with local system interdependencies.
AWS has infrustructure services in different catgeories : Compute, Storage, Database, Security, Management, Networking. Thus offering a high degree of architecture flexebility. Cutomers can power up Web & Mobile apps, Data processing and Warehousing, Storage and archiving.
Compute services
They allow customers to Develop, Deploy, Run & scale workloads. They are the compute building blocks and comes with a large variaty of hardware configurations. Their software are customizeable at launch trough AMI. Can be used with auto scaling and load balancers.
-
Amazon EC2 : Amazon Elastic Compute Cloud.
A web service that provides resizeable secure compute capacity in the cloud.
compute capacity refers to that functionality that is traditionally provided by on premises and virtual servers.
-
Amazon EC2 Auto Scaling.
Customer can maintain the health and availability of their applications by setting triggers to automatically increase/decrease the number of instances (horizontal scaling) as well as the hardware of the instance (vertiacal scaling)
automatically add/remove EC2 instances to adapt to demand.
-
It can monitor the health of running instances. When an instance fails the health check it will get terminated and replaced by a new one.
-
It also automatically balance instances across zones.
-
Ensure Dynamic and Predictive Scaling
-
-
Amazon ELB : Elastic Load Balancing.
It increases availability and fault tolerance of apps.
Distributes application traffic across multiple targets : EC2 instances, containers, IP adresses and lamda functions. in one or more availability zones.
It is scalable and acts at the region level (distribute traffic across multiple AZ within a single region).
The load balancer sends requests only to healthy instances which are configured by the customer.
They can offload encryption and decryption so that instances only needs to focus on their main work.
There are three types of load balancers :
- Application load balancer.(For web apps with http and https)
- Network load balancer.(more resilient on traffic spikes)
- Classic load balancer.(previous generation load balancer for EC2 classic instances)
-
AWS Lambda.
Runs code without server management. It is referred as serverless computing. Codes are run withtin milliseconds of an event
-

-
AWS Fargate (serverless) :
It works with both Amazon ECS and Amazon EKS. It is a serverless compute engine for containers. It works with both Amazon Elastic Container Service (ECS) and Amazon Elastic Kubernetes Service (EKS). Fargate makes it easy for you to focus on building your applications. Fargate removes the need to provision and manage servers, lets you specify and pay for resources per application, and improves security through application isolation by design. Fargate allocates the right amount of compute, eliminating the need to choose instances and scale cluster capacity. You only pay for the resources required to run your containers, so there is no over-provisioning and paying for additional servers. Fargate runs each task or pod in its kernel providing the tasks and pods their own isolated compute environment. This enables your application to have workload isolation and improved security by design.

The AWS Free Tier enables you to begin using certain services without having to worry about incurring costs for the specified period.
Three types of offers are available:
- Always Free
- 12 Months Free
- Trials
- Pay for usage (On Demand): For each service, you pay for exactly the amount of resources that you actually use, without requiring long-term contracts or complex licensing.
- Pay less when Reserving: Some services offer reservation options that provide a significant discount compared to On-Demand Instance pricing.
- Pay less with volume-based discounts when using more: Some services offer tiered pricing, so the per-unit cost is incrementally lower with increased usage.
The AWS Pricing Calculator lets explore AWS services and create an estimate for the cost of use cases on AWS. AWS estimates can be organized by groups that can be defined. A group can reflect how the company is organized, such as providing estimates by cost center.
exmaple :
- AWS Lambda : It offers 1 Million free request per Month. The lambda has a maximum execution time of 15 minutes, so it can be used to run this log backup process.
