AWS Basic Architecture
Basic Architecture of AWS
Starting from A to Z, almost everything is available under the same roof on Amazon. One of our many services includes EC2 which is Elastic Compute Cloud. EC2 provides users to use virtual machines with varied configurations as and when they need them. This web service of ours offers various configuration options, mapping of an individual server, various pricing options, secure and resizable compute capacity, etc. all these are done with the minimal effort of the user. Its structure consists of S3 that helps the user to keep any information or data securely. We have built this service provider keeping in mind the user’s safety and the process of retrieving information.
Balancing The Storage Capacity
To improve the application, usage, and efficiency of EC2 the load balancing feature is extremely vital. The structure pivots around this feature since it refers to the software or hardware load over the servers. In this light, load balancing becomes very important. Hardware load balancer happens to be a very regular network appliance that is used in several mainstream architectures. AWS also caters to related services, for instance, Elastic Load Balancing Service allocates the traffic to EC2 over a multitudinous yet available source. The Elastic Load Balancing inflates and deflates the capacity of load-balancing for adjusting to jam demands.
Storehouse Of Data
Amazon Cloud-front shoulders the responsibility for delivery of content which is utilized towards the delivery of the website. This might happen to contain static, streaming and dynamic content with the use of a widespread network of locations. The user’s demand and requests content are routed and channelized automatically to the edge location near to them improving the performance of the cloud-front in the process.
This has been optimized to be in sync to work with a variety of other Amazon Web Services namely Amazon EC2 and the Amazon S3. Amazon Cloud-front also works suitably well along with any server that does not have its origin in the AWS and holds the original files simultaneously in the same manner.
The best feature of AWS is that you pay only for the service used. There are no contracts or minimum commitments. You shall only pay only the service least or most services received.
Performance Improving Feature
The Elastic Load Balancer feature allows us to distribute the traffic to servers. Following this, it improves the performance of the EC2. This characteristic feature of AWS, which distributes the traffic to the web servers, is allocated to EC2 instances over zones available in manifolds.
Managing The Security Of Data
EC2 is built a security group feature that resembles the inbound network firewall. This feature allows us to mention the ports, protocols, and source of IP ranges, reaching the EC2 instances. Of these instances, each can be hitched with more than one security group that send certain traffic to each of the instances.
Managing Memory Cache In Cloud
Another service of Amazon is the Elastic Cache. This web service is configured to manage cache in the cloud without losing the data or any other stored information. A cache is pivotal in memory management and reduces the load by improving scalability and performance on the tier by capturing information that is frequently used.
Amazon Relational Database Service
Amazon RDS is similar to the likes of Oracle, MySQL, or SQL Server database. For Amazon RDS you can use the same applications, queries, and tools. The software is automatically patched and it also provides backups according to the instruction of the user by supporting the recovery. No investments are required and payment is taken only for used resources.
EC2 Instances – Hosts For RDMS
Amazon RDS enables the installation of RDBMS (Relational Database Management System) like Oracle, MySQL, DB2, SQL Server, etc. on an EC2 instance.
The availability of simple disks rises when the Amazon EBS volumes automatically manage redundancy within the availability zone. In case, there is an insufficient volume for our database needs, it can be included to inflate the performance of the same.
Stacking Data And Back-Ups
AWS cloud puts forth numerous options for accessing, storing, and providing a back up for web application assets and data. These are kept safe without the fear of losing them in case of a breakdown or technical crash down. Amazon S3 is a web-service providing interface, used for storing and retrieving data of any amount. You can do so at your own time and from any domain.
Amazon S3 stocks data within resources known as buckets. You can stock up as many volumes as you may in the bucket and utilize them for reading, writing and deleting data from bucket later. EBS volumes may be expanded up to 1 TB and these may also be striped for bulkier volumes. The provisioned IOPS volumes are configured to cater to the requirements of database workloads. These are responsive to consistency and storage performance and the user has to be extremely careful with it. 1,000 IOPS/ volume is the present support rate of the EBS.
Salient Feature
The striking difference between the traditional hosting model and AWS architecture is that the former can scale the fleet of the application to handle the traffic. As per the model for traditional web hosting, models on traffic forecasting generally provision hosts ahead of projected traffic.
Vital Points for Web Hosting in AWS
Key considerations are listed down below:
- You do not need a physical network device
- Routers, firewalls, and load-balancers are no longer built on devices
- these have been replaced with multiple software solutions to ensure quality in the available solutions
- for balancing loadHAProxy, Zeus, Pound, Nginx, etc should be the immediate choices
- A VPN connection can very well be established using OpenSwan, OpenVPN, Vyatta, etc.
Security and Safety Measures
To lock down every host, AWS is a more secure model than most other models available. The security groups in EC2 are specially formulated for every host. A variety of lucid and stratified security models may be generated to enable minimized host access as per needs.
Customer Helpline
You can easily avail of the EC2 instances at most AWS availability zones.
