What is AWS ?

What is AWS ?

or What is Amazon Web Service ? AWS or Amazon web service is a platform that offer Reliable, flexible, scalable and cost-effective cloud computing service. We can server access, database access, storage access and access to high level application components within Seconds remotely. We can consider them as a temporary and disposable resources. Amazon web services is free from inflexibility, in-constrain and infinite IT infrastructure.

  WHY AWS ?

AWS can reduce risk: Cloud Computing user’s agile to reduce risks. Like cost risk & security risk

Scale IT Infrastructure: Ability to resize your resources as necessary. Customer can grow and shrink the size of server.

Operations during disaster: AWS service that makes it quick and easy to shift your disaster recovery strategy to AWS cloud from existing physical or virtual data centers, private clouds, or any other public clouds

Secure data: 24/7 security is provided by the AWS.

  AWS CORE SERVICES:

AWS Compute

AWS EC2 – Amazon Elastic Compute Cloud allows you to easily scale virtual machines for your main compute horsepower. It is a web service that provide secure, resizable compute capacity in the cloud. It is designed to make scaling of cloud computing easier. It provides complete control on computing resources. The instances are pay as you go, Broad selection of hardware / software and Global Hosting.

In just minutes can launch virtual machines called instances online. Select Amazon Machine Image (AMI) with operating system of your choice (Linux or Windows) and start deploying your clusters. There are three types of popular instance when creating AWS EC2 instances:

AWS Compute optimized – Instances that require extremely high request rates. This Compute optimized configuration leverages industry leading processors.

AWS Memory optimized – These instances are built with the most efficient per Gigabyte memory cost.

AMS Storage optimized – Storage optimized instances are accessed extremely fast SSD storage to serve data retrieval requests with high speed.

  AWS Storage

Amazon S3 – Amazon AWS S3 simplifies all of your storage needs into containers called buckets, then it let you choose where and how to store them

There are four ways to designate buckets in Amazon Web Service. Cost to store them varies greatly.

1) Amazon AWS S3 Standard Storage

Standard storage is for data that are frequently accessed, such as logs for the last 1 day or a file that is being accessed frequently. It offers affordable, highly available storage capacity that can grow as quickly as organization needs. Service is charged by the GB used and number of requests to access, delete, list, copy or getting a data in Amazon S3

2) Amazon AWS S3 Infrequent Access Storage

To manage and monitor resources that are necessary for your operation but are used less frequently. Buckets has infrequent access and high data availability (99.9%). Cost effective per gigabyte than Standard Storage buckets.

3) Amazon Glacier

For deep storage data that must be retained but are used rarely. It provides long term archiving solution. Data stored in Glacier can take hours to retrieve, but the cost is less of standard storage.

4) Amazon S3 Reduced Redundancy Storage

This Bucket stores non-essential & easily reproducible data, with variable amount of redundancy and durability as their higher-level storage.

AWS EBS – AWS Elastic Block Storage provides persistent Block-level storage volumes for your Amazon EC2 instances with low latency. Also it allows system to access high speed SSD storage and layer your security with Access Control Lists and encryption. Elastic Block Store permits the use of MDD or SDD storage for many purposes, including boot volumes for Amazon EC2 instances.

AWS Database

AWS RDS – Amazon Relational Database Service makes it easy to set up, operate, and scale any relational database in the cloud. It provides cost-efficient & resizable capacity with automating time-consuming administration tasks. Amazon RDS is adaptable on several database instance types like optimized for memory, performance or I/O. It supports encryption, automated backups are, user-initiated snapshots and auto update of database software.

AWS DynamoDB: NoSQL database in the cloud with blazing performance and on demand scalability. Database management is smoother as it auto manages the data traffic of tables over multiple servers and maintains performance. It can relieves the customers from the burden of operating and scaling distributed databases. Hardware provisioning, configuration, replication, setup, software patching, cluster scaling is handled automatically on this service.

AWS Elasti Cache : It creates in memory caches for better performance interaction ,also this service supports open standards in caching

AWS Networking

VPC – Virtual Private Cloud provides the networking components needed for an infrastructure including subsets, gateways, routing tables, and security mechanisms AWS VPC flow logs are detailed records of the IP traffic passing to and from a port, subnet or your entire Amazon VPC environment. Flow logs provide the deep detailed analytics on who is going where and when. This information provided about your network will enable you develop architecture and budget plans for ongoing operations and overall helps in robust network management. Amazon VPC flow logs also allows you to conduct network forensics including what traffic is worth the compute and storage cost of capturing.

AWS Management

AWS Cloud Watch – Permits the monitoring of key services; uses metrics and alarms for a familiar monitoring approach. Creating an alarms which watch metrics and send notifications or automatically make changes to the resources. Able to monitor when a threshold is breached. For example, when we monitor the CPU usage and disk reads and writes the Amazon EC2 instances & then use this data to determine whether possible to launch additional instances to handle increased load. With Amazon Cloud Watch, we can gain system-wide visibility into application performance, resource utilization, & operational health.

AWS Cloud Trail – AWS Cloud Trial is a service that enables governance, compliance, risk auditing and operational auditing of your Amazon AWS account. It permits the tracking of potentially all the API calls to AWS, also allows you detailed analysis of all events no matter the source is. With this service you can login and continuously monitor and retain account activity on your AWS infrastructure. Amazon Cloud Trail provides event history of your AWS account activity such as actions taken through the AWS Management Console, command line tools, AWS SDKs and other AWS services.

AWS Security

AWS IAM – Identity and Access Management allows the creation of users, groups, and roles for interacting securely with Amazon Web Services.

Helps to manage AWS IAM users and their access

Helps to manage AWS IAM roles and their permissions.

Helps to manage federated users and their permissions.

AWS Application Integration

AWS SNS: The Simple Notification Service allows the generation of email and text notifications based on Amazon Web Services events. It is a highly available, durable, secure, fully managed pub/sub messaging service that enables you to decouple micro services, distributed systems, and non-server applications.

AWS SQS: The Simple Queue Service assists you in decoupling components and queuing messages between these components. This service helps the use of micro services for your processing needs.

WHAT IS CLOUD COMPUTING ?

WHAT IS CLOUD COMPUTING?

Cloud Computing is accessing data remotely over the Internet. It can provide services over the network (public or private). Cloud computing refers to Internet based Computing i.e., Configuring, Manipulating and Accessing the applications online. Here virtual shared servers provide software, infrastructure, and platform and data storage. It is a combination of both software and hardware-based computing resources and delivered as network service.

Diagram Label – Secured Cloud Computing Architecture

What Are Benefits Of Cloud Computing ?

Efficiency/Cost Reduction: Cloud plays a vital role in IT infrastructure management by providing efficient reliable server availability also reduce costs related to downtime. We don’t have to spend time and money on fixing potential issues related to downtime.

Data Security on Cloud: Cloud offers many advanced Security features to ensure data is securely stored and handled. Cloud storage providers implement the baseline protections for their platforms and the data they process, authentication, access control and encryption.

Scalability: In a business, we don’t have the same IT requirements as a start-up. Using cloud is a great solution because it enables an enterprise to decide efficiently and quickly to Scale up/down an IT Infrastructure. If business demand increase, we can easily increase the cloud capacity without having to invest on physical infrastructure.

Data Mobility: Data in the cloud is easily stored, retrieved, recovered and processed. We can access from any corner of the world as long as we are connected to internet. This saves time and team effort maintaining systems and reducing IT workloads.

Disaster Recovery: Data loss is a serious problem in any organization, along with data security. Storing data in the cloud guarantee that data is available, even if our laptops or computers are damaged. If we upload data on cloud, it remain accessible to any authorized computer with an internet connection. Thus it can be a good addition to disaster recovery plan template of an organization.

  Pros and Cons Of Cloud Computing

Pros:

Access documents from anywhere, including computers and mobile devices. It can also Auto Sync data, so that update can be shared with all the connected devices.

Creating document in web browser, multiple editors can access the documents.

Interface make it easy to clear surveys with many types of questions and logic. Surveys are easily distributed online.

Immediate to host. No need to order and set up server. Flexible configuration expand memory or storage.

Cons:

Technical issues: Cloud totally depends on internet access, if any network or connectivity problems will render the setup. It might take several minutes for cloud to detect server launch.

Dependency and vendor lock: If a user switch to some other provider, it is difficult to transfer huge data from old provider to new one.

Increased Vulnerability: if proper virtual cloud is not in place it may lead to spam access

    3 Types Of Cloud Computing

Platform as a service (PAAS): Used to design, develop, built and test applications which are provided mainly by the cloud infrastructure.

For example: Azure service platform, force and Google app engine.

Infrastructure as a service (IAAS): This is pay as you use model. Services like storage, database management and compute capabilities are offered on demand.

For example: Amazon web services, Go grid, 3 Tera.

Software as a service (SAAS): Highly scalable internet based applications are hosted on the cloud and offer as services to end user.

For example: Google docs, acrobat, salesforce.
