SCALABILITY... AWS Winning Power. HOW???

A fast growing online-marketing hub realises that as a result of massive promotion, roadshows and recommendations from satisfied customers, their clients base has increased by 300% in the last 18 months, so their former database 
 hosted on cloud is nolonger running as ast as before, so they consulted a cloud engineer who is also a database management specialist.
Here is His professional advice, leveraging on the SCALABILITY of AWS(Amazon Web Services).How can the scalability of AWS help solve the company's dababase challenges?
Amazon Web Services (AWS) is designed to provide scalable and elastic computing resources to meet the demands of various applications and workloads. Scalability in AWS refers to the ability to quickly and efficiently adjust the resources (such as computing power, storage, and networking) allocated to your applications based on changing workload requirements. There are two main types of scalability in AWS:

Vertical Scalability a.k.a Scaling Up:
Vertical scalability involves increasing the capacity of a single instance by adding more resources, such as CPU, memory, or storage. In AWS, you can vertically scale Amazon EC2 instances by choosing larger instance types with more resources. This can be done manually or automatically using features like Auto Scaling and Amazon EC2 Auto Scaling Groups.

Horizontal Scalability a.k.a Scaling Out:
Horizontal scalability involves adding more instances to your application's environment to distribute the workload and accommodate increased traffic. AWS provides several services and features that facilitate horizontal scalability:

Auto Scaling: AWS Auto Scaling allows you to automatically adjust the number of instances in response to changes in demand. It helps ensure that you have the right number of instances available to handle varying levels of traffic without overprovisioning.

Load Balancing: AWS offers load balancing services, such as Amazon Elastic Load Balancing (ELB), that distribute incoming traffic across multiple instances. This improves application availability and performance, while also enabling you to add or remove instances as needed without affecting end users.

Elastic Beanstalk: This Platform-as-a-Service (PaaS) offering by AWS handles the provisioning and management of resources for your application. It automatically scales your environment based on defined metrics or triggers.

Amazon RDS Read Replicas: For database workloads, you can use read replicas to horizontally scale database read operations by replicating data across multiple instances.

Amazon DynamoDB: This NoSQL database service automatically scales to accommodate growing workloads and offers seamless horizontal scaling with no manual intervention.

Amazon S3: Amazon Simple Storage Service automatically scales to handle virtually unlimited amounts of data.

Amazon Aurora: This relational database engine offers high performance and scalability, with the ability to add read replicas and automatically adjust resources.

AWS Lambda: AWS Lambda enables you to run code in response to events, automatically scaling to handle workloads without the need for provisioning or managing servers.

The combination of these features and services allows you to design and build applications that can scale both vertically and horizontally to accommodate varying levels of traffic and usage, ensuring optimal performance and cost efficiency.
NB: AWS is a better option when it comes to storing an organisation's database in the cloud. it is cost effective.
