AWS SERVICES -

A.  EC2 - Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides secure, scalable compute capacity in the cloud.  It is like a web server that can be resized according to number of configuration.  Resizable compute capacity in the cloud , which can be customize according to your need . It is used to host your a application .
B. Lambda - AWS Lambda is a compute service that makes it easy for you to build applications that respond quickly to new information . This is an aws service that executes background tasks.It is not used to host an application. example : file compression in background .
AWS Lambda is an event-driven, serverless computing platform provided by Amazon as a part of the Amazon Web Services. It is a computing service that runs code in response to events and automatically manages the computing resources required by that code. 
C. Elastic Beanstalk - AWS Elastic Beanstalk is an easy-to-use service for deploying and scaling web applications and services developed with Java, .NET, PHP, Node.js, Python, Ruby, Go, and Docker on familiar servers such as Apache, Nginx, Passenger, and IIS.You can simply upload your code and Elastic Beanstalk automatically handles the deployment, from capacity provisioning, load balancing, auto-scaling to application health monitoring. At the same time, you retain full control over the AWS resources powering your application and can access the underlying resources at any time.There is no additional charge for Elastic Beanstalk - you pay only for the AWS resources needed to store and run your applications.
D. Elastic Load Balancer - It distributes the workload on the deployed instances . As if the server load in more during 5 to 9 pm then it will distribute it among all servers you have for a better performance . 
E. AutoScaling - AWS Auto Scaling lets you build scaling plans that automate how groups of different resources respond to changes in demand. You can optimize availability, costs, or a balance of both. AWS Auto Scaling automatically creates all of the scaling policies and sets targets for you based on your preference. Auto Scaling and Elastic Load balancer are used together .

AWS STORAGE SERVICES -

a. S3 - Amazon Simple Storage Service (Amazon S3) is an object storage service that offers industry-leading scalability, data availability, security, and performance. This means customers of all sizes and industries can use it to store and protect any amount of data for a range of use cases, such as websites, mobile applications, backup and restore, archive, enterprise applications, IoT devices, and big data analytics. Amazon S3 provides easy-to-use management features so you can organize your data and configure finely-tuned access controls to meet your specific business, organizational, and compliance requirements. Amazon S3 is designed for 99.999999999% (11 9's) of durability, and stores data for millions of applications for companies all around the world.

b. Cloud Front - Amazon CloudFront is a fast content delivery network (CDN) service that securely delivers data, videos, applications, and APIs to customers globally with low latency, high transfer speeds, all within a developer-friendly environment. CloudFront is integrated with AWS – both physical locations that are directly connected to the AWS global infrastructure, as well as other AWS services. In short what it does that it "connect you to your nearest server to give a quick response " .

c. Elastic Block Storage(EBS) - Amazon Elastic Block Store (EBS) is an easy to use, high performance block storage service designed for use with Amazon Elastic Compute Cloud (EC2) for both throughput and transaction intensive workloads at any scale. A broad range of workloads, such as relational and non-relational databases, enterprise applications, containerized applications, big data analytics engines, file systems, and media workflows are widely deployed on Amazon EBS. We can use EBS only with  EC2 .one EC2 can have multiple EBS but vice-versa is not true . 

d.  Amazon-Glacier -Amazon S3 Glacier and S3 Glacier Deep Archive are a secure, durable, and extremely low-cost Amazon S3 cloud storage classes for data archiving and long-term backup. They are designed to deliver 99.999999999% durability, and provide comprehensive security and compliance capabilities that can help meet even the most stringent regulatory requirements. Customers can store data for as little as $1 per terabyte per month, a significant savings compared to on-premises solutions. To keep costs low yet suitable for varying retrieval needs, Amazon S3 Glacier provides three options for access to archives, from a few minutes to several hours, and S3 Glacier Deep Archive provides two access options ranging from 12 to 48 hours. " They are basically used for data archiving services , offering low price , so slow in speed , We store that data in glacier that are not frequently accessed".

e. Snowball - With Snowball, you don’t need to write any code or purchase any hardware to transfer your data. Simply create a job in the AWS Management Console ("Console") and a Snowball device will be automatically shipped to you. Once it arrives, attach the device to your local network, download and run the Snowball Client ("Client") to establish a connection, and then use the Client to select the file directories that you want to transfer to the device. The Client will then encrypt and transfer the files to the device at high speed. Once the transfer is complete and the device is ready to be returned, the E Ink shipping label will automatically update and you can track the job status via Amazon Simple Notification Service (SNS), text messages, or directly in the Console.

AWS DATABASE SERVICES -

a . RDS - It is a relation database management service . The thing you need to understand that it is not the database it is database management service . It provides cost-efficient and resizable capacity while automating time-consuming administration tasks such as hardware provisioning, database setup, patching and backups. It frees you to focus on your applications so you can give them the fast performance, high availability, security and compatibility they need.
b. Aurora -Amazon Aurora is a MySQL and PostgreSQL-compatible relational database built for the cloud, that combines the performance and availability of traditional enterprise databases with the simplicity and cost-effectiveness of open source databases.Amazon Aurora is up to five times faster than standard MySQL databases and three times faster than standard PostgreSQL databases. It provides the security, availability, and reliability of commercial databases at 1/10th the cost. Amazon Aurora is fully managed by Amazon Relational Database Service (RDS), which automates time-consuming administration tasks like hardware provisioning, database setup, patching, and backups.
c. Dynamo DB - Amazon DynamoDB is a fully managed proprietary NoSQL database service that supports key-value and document data structures and is offered by Amazon.com as part of the Amazon Web Services portfolio. DynamoDB exposes a similar data model to and derives its name from Dynamo, but has a different underlying implementation .  The main advantage of using it that you don't need to specify space for data .As the data comes in the space manages automatically .
d. ElastiCache - Amazon ElastiCache is a fully managed in-memory data store and cache service by Amazon Web Services. The service improves the performance of web applications by retrieving information from managed in-memory caches, instead of relying entirely on slower disk-based databases. So it basically works as the cpu cache monitor . When program needs a data it goes to cpu if it not present there then it goes to main memory . It makes the process faster . 

AWS NETWORKING SERVICES -

a. VPC - Amazon Virtual Private Cloud (Amazon VPC) enables you to launch AWS resources into a virtual network that you've defined. This virtual network closely resembles a traditional network that you'd operate in your own data center, with the benefits of using the scalable infrastructure of AWS.

b. DirectConnect- AWS Direct Connect is a cloud service solution that makes it easy to establish a dedicated network connection from your premises to AWS. Using AWS Direct Connect, you can establish private connectivity between AWS and your datacenter, office, or colocation environment, which in many cases can reduce your network costs, increase bandwidth throughput, and provide a more consistent network experience than Internet-based connections.AWS Direct Connect lets you establish a dedicated network connection between your network and one of the AWS Direct Connect locations.

c. Route 53 - Amazon Route 53 is a highly available and scalable cloud Domain Name System (DNS) web service. It is designed to give developers and businesses an extremely reliable and cost effective way to route end users to Internet applications by translating names like www.example.com into the numeric IP addresses like 192.0.2.1 that computers use to connect to each other. Amazon Route 53 is fully compliant with IPv6 as well.

AWS SECURITY SERVICES - 

1. IAM - AWS Identity and Access Management (IAM) is a web service that helps you securely control access to AWS resources. You use IAM to control who is authenticated (signed in) and authorized (has permissions) to use resources.

When you first create an AWS account, you begin with a single sign-in identity that has complete access to all AWS services and resources in the account. This identity is called the AWS account root user and is accessed by signing in with the email address and password that you used to create the account. We strongly recommend that you do not use the root user for your everyday tasks, even the administrative ones. Instead, adhere to the best practice of using the root user only to create your first IAM user. Then securely lock away the root user credentials and use them to perform only a few account and service management tasks.

2. KMS(key management service) - AWS Key Management Service (KMS) is an Amazon Web Services product that allows administrators to create, delete and control keys that encrypt data stored in AWS databases and products. ... The service allows admins to create keys and usage policies; they also can enable logging .

If you know the concept of public and private key , it is pretty much similar to that .

AWS APPLICATION SERVICES - 

a. SES (simple email services) - Amazon Simple Email Service (Amazon SES) is a cloud-based email sending service designed to help digital marketers and application developers send marketing, notification, and transactional emails. It is a reliable, cost-effective service for businesses of all sizes that use email to keep in contact with their customers.You can use our SMTP interface or one of the AWS SDKs to integrate Amazon SES directly into your existing applications. You can also integrate the email sending capabilities of Amazon SES into the software you already use, such as ticketing systems and email clients.

 b. SQS (simple queue service) - Amazon Simple Queue Service (Amazon SQS) is a distributed message queuing service introduced by Amazon.com in late 2004. It supports programmatic sending of messages via web service applications as a way to communicate over the Internet. SQS is intended to provide a highly scalable hosted message queue that resolves issues arising from the common producer-consumer problem or connectivity between producer and consumer.

Amazon SQS can be described as commoditization of the messaging service. Well-known examples of messaging service technologies include IBM WebSphere MQ and Microsoft Message Queuing. Unlike these technologies, users do not need to maintain their own server. Amazon does it for them and sells the SQS service at a per-use rate.

c. SNS(simple notification service) - Notification services based on triggers . For example -if an image will be uploaded it will send notification to SQS and SES with all information and then SES can send it to bulk users.
