BENEFITS OF EC2
Users of AWS EC2 must be familiar with the EC2 components, operating system support, security measures, pricing structures, and so on.
Assistance for Operating Systems- Amazon EC2 supports several operating systems for which we must pay additional licencing fees, including Red Hat Enterprise Linux, SUSE Enterprise Linux, and so on. The Amazon Virtual Private Cloud must be used in conjunction with these operating systems (VPC).
Security- The visibility of an AWS account is completely under the hands of the user. AWS EC2’s security systems let you create groups and assign running instances to them as needed. You can define which groups can interact with each other, as well as which IP subnets on the Internet can connect.
Pricing- Depending on the type of resources, applications, and databases, AWS offers a variety of price choices. It enables users to customise their resources and calculate prices accordingly.
Tolerance to faults- Amazon EC2 gives consumers access to its resources in order to create fault-tolerant applications. Elastic Compute Cloud furthermore contains geographical areas and secluded sites well-known as availability zones which assist in fault tolerance and stability. For security concerns, it does not provide the specific locations of regional data centres.
When users launch an instance, they must choose an AMI that is located in the same region as the instance. In order to provide uninterrupted facilities in the event of a failure, instances are distributed across many availability zones, and Elastic IP addresses, also known as EIPs, are utilised to translate unsuccessful instance addresses to simultaneously operational instances in other zones, eliminating service delays.
Migration- Users can utilise this service to migrate existing apps to EC2. Data loading costs $80.00 per storage device and $2.49 per hour. This service is best for users that have a lot of data to migrate.
AWS EC2 INSTANCES
Elastic Compute Cloud Instances are virtual atmospheres that are separate from the On-demand service’s base. Here, an EC2 user can hire a virtual server, or “instance,” as needed, and effectively migrate or attach apps to it. As previously said, you may easily raise or decrease the number of ec2 instances based on the website traffic dynamics. AWS EC2 instances also save you from the need to invest in and manage additional hardware and software.
To meet customer needs, Amazon offers a variety of instances with diverse CPU, memory, storage, and networking resource options. All of the kinds are offered in a range of sizes to accommodate various workloads.
Amazon Machine Images are utilised to build instances (AMI). The graphics of the machines are similar to templates. They have an operating system (OS) and other software installed that establish the user’s operational environment. Users can choose from AWS’s AMIs, the user community’s AMIs, or the AWS Marketplace. Users can also design and share their own AMIs.
Features of EC2 instance-
The features of an Amazon EC2 instance are as follows:
- Several of the features offered by the Elastic Compute Cloud can be customised. These features comprise the storage, memory and the number of virtual processors that are obtainable to the instance.
- Amazon’s Elastic Block Storage service permits block-level storage capacities to be combined with EC2 instances and consumed as hard drives, including Linux, Microsoft Windows Server, and others.
- Amazon’s Elastic IP solution allows IP addresses to be associated with an instance and allows you to raise or reduce the amount of storage accessible to an EC2 instance while attaching EBS volumes to multiple instances at the same time.
- Deprived of the support and aid of a network supervisor, flexible IP addresses can be shifted from one instance to another. As a result, they’re perfect for use in failover clusters, load balancing, and other scenarios where numerous servers are executing the same service.
- They have Amazon Machine Image templates pre-configured. Servers and operating systems can benefit from these images.
- The Amazon ecosystem offers a variety of instance kinds. They offer a variety of options for configuring the RAM, CPU, storage, and networking of your instance.
- Extremely secure to use, with a password-protected login and key pairs.
- The instance data can be put in safekeeping in the given storage volume. When the instance stops working, the data on these instance storage volumes is erased.
- It takes advantage of Amazon EBS Volumes to store your data indefinitely.
- Regions and Availability Zones provide the support. They also provide various sincere places for the resources. Instances, Amazon EBS Volumes, and other resources are included.
- It has a firewall that lets you decide which ports, protocols, and source IP ranges are allowed to access your instance. Security Groups are used to set this up.
- The examples created by you have an ever-changing IP address by default. Elastic IP Addresses can be used to allocate a static IP address to your case.
- You can use Tags to give metadata for your instances.
- Using Virtual Private Clouds, consumers may be able to arrange their network to be separated from the rest of the AWS Cloud (VPC)
EC2 instance types-
Based on the desired application profiles, instance types are classified into families. The succeeding is few of such groups:
- General Purpose Instance: It can be utilised for anything. A general-purpose instance is a virtual machine that can manage a wide range of tasks. The number of CPU cores, on-demand storage, and memory in general-purpose instances is optimised. Web server hosting and software development and testing are two common use cases for general purpose instances.
- Computed Optimised Instance: Computed optimised instances in the AWS cloud are designed to run big data applications that require a significant amount of power and storage. These instances are designed and tailored to execute computational and data-intensive applications which require an advanced number of I/O operations per second, as well as strong network performance and availability. Examples of applications include scientific and financial modelling and simulation, machine learning, enterprise data warehousing, and business intelligence.
- Graphics Processing Units or GPU: These instances make it possible to run graphics-intensive applications more quickly than normal EC2 instances. Gaming and design work are two examples of systems that use GPUs. GPUs are frequently used in Linux distributions to render graphical user interfaces, improve compression speeds, and speed up database queries, for example.
- Optimised Memory: A high-speed solid-state drive is used in memory optimised instances to enable ultra-fast data access and great performance. Open-source databases, real-time big data analytics, etc., are all good applicants for these instances, which demand more memory and less CPU power.
- Optimised Storage: Applications that demand high I/O speed, such as NoSQL databases that save and retrieve data in real-time, benefit from storage optimised instances. They’re also ideal for memory-intensive activities including data processing, data warehousing, analytics, and log processing.
Benefits of Elastic Compute Cloud Instances in Amazon Web Services-
