Cloud is always remain hot topic for discuss security,
performance and high-availability. Many of organizations have moved on cloud
and many of planning to move, It is the toughest job to decide which cloud architecture is
best for your organization, there are having so many ways where we can easily
understand cloud architecture, what we exactly want for run your infrastructure in cloud and most
of the organizations are followed traditional infrastructure.
Amazon is provide same modernize traditional infrastructure
in cloud which is the best suitable for all organization. The traditional
infrastructure is easily portable to the cloud services provided by the AWS
products with only few simple modifications. This section will helps you
evaluate an AWS cloud solution.
It compares deploying your web application in the cloud to
an on-premises deployment, presents an AWS cloud infrastructure for hosting
your application and discusses the key components of this solution.
If you are responsible for running a web application, you
face a variety of infrastructure and architectural issues for which AWS can
provide seamless and cost effective solution.
AWS Cloud
Architecture for Web Hosting
Below is another look at that classic web application
architecture and how it could leverage the AWS cloud computing infrastructure.
The following sections outline some of the key components of
web hosting architecture deployed in AWS cloud and explain how they are differ
from the traditional web hosting architecture.
Content delivery- Edge caching is still relevant in the AWS
cloud computing infrastructure, it is available in AWS which is to utilize the
Amazon cloud front services for edge caching your website.
Amazon cloud front can be used to deliver your website,
including dynamic, static and streamline content using a global network for
edge location. Requests for your content are automatically routed from the
nearest edge location, so content delivered with the best performance.
Managing DNS - moving a web application to the AWS cloud
requires some DNS changes to take advantage of the multiple availability zone
that AWS provides. To help your manage DNS routing, AWS provides Amazon 53, it
is highly available and scalable DNS web services. Queries for your domain are
automatically routed from the nearest DNS server and thus answered with the
best possible performance.
Host Security- Security groups features are available as a
firewall services which is helpful for stop unwanted traffic from the unwanted
network are allowed only specific ports and services for the specific network
or tier architecture. For the web tier only http and https should be
allowed and for the application tier
will communicate only with web tier and db tier internally.
Security groups are allowed to reach your EC2 instance.
Storage gateway- AWS
storage gateway is a service connection an on-premises software appliance
with cloud based storage to provide seamless and secure integration between an
organization’s on-premises IT environment and AWS storage infrastructure. This
service allow you to securely store data in the AWS cloud for scalable and cost
effective storage. It provides low-latency performance by maintaining
frequently assessed data on-premises while securely storing all of your data
encrypted in Amazon storage service (S3).
AWS storage Gateway
supports three configuration.
Gateway-Cached Volumes-
you can store your primary data in Amazon S3 and retain your frequently
accessed daily locally. Gateway-cached volumes substantial cost savings on
primary storage.
Gateway –Stored Volumes-
in the event you need low-latency access to your entire data set, you can
configure your on-premises data gateway to store primary data locally.
Gateway –Virtual Tape
library- if you have limitless data which should be securely stored in virtual
tape, you can use this storage to store data in tape library which may use for
future.
It is make very easy to
store on-premises data on Amazon S3 and Amazon Glacier, AWS storage gateway
reduce the cost, maintenance and scaling challenges associated with
managing primary, backup and archive storage environment. Amazon Gateway-Stored
and cached volumes are designed to seamlessly integrate with Amazon S3, Amazon
EBS and Amazon EC2 by enabling you to store point in time snapshots of your on-premises
application data in Amazon EC2 , S3 and EBS snapshots for future recovery
on-premises in Amazon EC2.
TNT drive is one of the
tool which will help to MAP Amazon S3 storage with Amazon VM instance.
