EC2 Features:

Functionality - EC2 offers its users a virtual computing platform that allows them to perform various operations, launch an EC2 instance and even create another one.

The security of virtual devices will be increased as a result. We can adjust our environment at any point during the life of a virtual machine using EC2 in addition to creating new virtual machines.

AMI ( Machine Image) choices that support several operating systems are included by default with EC2 and pre-configured resources like RAM, ROM, and storage. There are other choices besides these AMI possibilities.

Additionally, user-defined and default configurations can be combined to build AMIs. To save customers from establishing a new AMI each time, we can also save the user-definable AMI for further usage. Users can create a new EC2 device using an older reference rather than going through the complete process.

Operating System - EC2 offers a variety of operating systems that you can choose from when selecting your AMI. These options are not the only ones available. Users can also upload their operating system and choose that option when launching an EC2 instance. AWS currently offers the following operating systems.

  • Linux
  • Windows Server
  • Ubuntu Server
  • SUSE Linux
  • Red Hat Linux

Software - Because its users have access to a wide selection of EC2 alternatives, it has a monopoly on the cloud computing market. It offers a selection of software that users can run on their EC2 computers. AWS Marketplace offers the whole service. Among the software available on AWS are SAP, LAMP, and Drupal.

Scalability - We may scale up and down using the EC2 capability to our needs. This capability enables EC2 to handle all dynamic conditions with ease. Because of the adaptability of snapshots and volumes, it is quite dependable. Many businesses, including Flipkart, rely on this device whenever there is a lot of website traffic.

Let's now look at AWS Management Console's EC2 service.

First, login into your AWS account. You will be directed to the management console once you have logged in. Click on Services and then click on ECC2.

Afterward, you'll be redirected back to the EC2 console. This image shows various features of EC2.

What is EBS?

What is EBS?

A block storage service called Elastic Block Store is housed in the AWS cloud. Large amounts of data are kept in EBS in blocks that function as hard drives (called volumes). It can store data, including file system and transactional data, backup instances, containers, and software. EBS is frequently used in

EBS can be purchased through the AWS platform. AWS accounts are required. You can optimize pricing and performance with the platform. You can, for example, change volume type and size or delete duplicate volumes. You can also set up backup and recovery options from the platform.

Here are some backup options for you:

EBS replication - EBS automatically copies volumes within an Availability Zone. You'll always have a backup in case something happens to the volume.

AWS Backup - This is a paid service that AWS offers for an additional fee.

EBS snaps - point-in-time copies of your data that can be used as incremental backups. Learn more about EBS snapshots.

What is an EBS Volume?

An EBS volume can be described as a device that functions like a hard disk. EBS volumes can create file systems, store databases, and run applications. These are some of the most popular uses for EBS volumes.

Regular updates - data storage that requires frequent updates. Database applications and instance's system drives are examples.

High-throughput applications - that require continuous disk scans.

EC2 instances - Once you attach an EBS Volume to an EC2 Instance, the EBS volume acts as a physical hard drive.

EBS is frequently the default choice for less powerful EC2 instances because it was created for use with EC2 instances. EBS volumes are independent of EC2 and can be used as primary storage. As a result of its high availability and durability, EBS is perfect for demanding applications. EBS Volume Types

EBS offers two types of volume, each with a different price and performance. EBS Volumes can be divided into two categories:

  • SSD-backed volumes
  • HDD-backed volumes

SSD

  • SSD stands for Solid-state Drives.
  • SSD storage was launched in June 2014.
  • It can be used for general storage purposes.
  • It can support up to 4000 IOPS, which is very high.
  • SSD storage is extremely efficient but can be quite costly compared to HDD storage.
  • SSD volume types can be optimized for transactional workloads, such as frequent write/read operations with small I/O sizes. The performance attribute is IOPS.

SSD can be further divided into two parts:

  • SSD for General Purpose
  • Provisioned IOPS SSD

SSD for General Purpose

  • A General Purpose SSD can also be referred to by the term a GP2.
  • It is a general-purpose SSD volume that offers both performance and price.

With up to 10,000 IOPS, you can get 3 IOPS per gigabyte and the possibility to explode up to 3000 IOPS over a longer period for volumes above 3334 GiB. If you can get less than 10,000 IOPS, GP2 is the better option as it offers you the best performance and lowest price.

Provisioned IOPS SSD

  • It's also known as IO1.
  • It is used primarily for high-performance applications like intense applications and relational databases.
  • It is ideal for I/O-intensive applications, such as large relational and NoSQL databases.
  • This is for when you need more than 10,000 IOPS.

HDD

  • It stands for Hard Disk Drive.
  • The NSA introduced HDD-based storage in 2008.
  • HDD-based storage can be anywhere from 1 GB up to 1TB in size.
  • It can handle up to 100 IOPS, which is quite low.

HDD with Optimized Throughput

  • It is also known as ST1.
  • The Throughput Optimized HDD HDD is a low-cost HDD designed for applications that need higher throughput, up to 500 MB/s.
  • It is helpful for applications that need the data to be frequently accessed.
  • It's used to process log data, Big data, Data warehouses, and Log processing.
  • It cannot contain a boot volume. If Windows Server is installed on a C: drive, C: drive cannot be a Throughput Optimization Hard drive. D: drive or another drive could be.
  • You can choose between 500 GiB and 16 TiB for the Throughput Hard Disk.
  • It can support up to 500 IOPS.

Cold HDD

  • It is also known as the SC1.
  • It is the cheapest storage option for applications that are not frequently accessed.
  • It's useful for data that is not often accessed.
  • It is used primarily for File servers.
  • It can't be a boot volume.
  • The Cold Hard disk's size can range from 500 GiB to 16 Tb.
  • It can support up to 250 IOPS.

Magnetic Volume

  • It is the lowest-cost storage per gigabyte among all EBS volume types.
  • This is perfect for applications that require data access frequently.
  • It is ideal for applications that require low storage costs.
  • Magnetic volume is the only hard drive that is bootable. It can therefore be used as a boot disk.

What is AWS CloudWatch, and how can it help you?

What is AWS CloudWatch, and how can it help you?

For both AWS services and cloud applications, Dedicated CloudWatch Developers offers a unified monitoring solution. It keeps track of operational metrics from resources, including EC2 instances, RDS databases, VPCs, and Lambda functions, as well as log files from those resources.

You may build a stream, set off alarms, and take appropriate action for certain conditions while keeping an eye on your AWS account and its resources with AWS CloudWatch.

You have access to AWS resources thanks to AWS CloudWatch. You can monitor data like resource utilization, application performance, and operational health. Using these insights, you can control your application and keep the system operating smoothly.

What is AWS CloudWatch exactly?

AWS CloudWatch consists of two distinct services, which are promoted under the common title "CloudWatch."

  • Metrics services to measure and manage operational metrics and resource performance.
  • A logging service that captures, stores, and manages service and application logs.

The Metrics service captures and stores resource metric data. It also provides alarms, event filtering, and dashboards. CloudWatch Events is the event service, and CloudWatch Alarms is the alarm service.

CloudWatch Logs is the Logging service. It provides log data storage and archiving, as well as a basic log viewer and query facility called top CloudWatch developers.

Naming Confusion

CloudWatch can be confusing as Logs and Metrics are presented together in one service. In reality, they are two separate services.

The logging service that causes misunderstanding is CloudWatch Logs, but the metrics service is not.

Each service's confusing features include CloudWatch Events, CloudWatch Alarms, and CloudWatch Logs Insights, to name just a few. Additionally, many AWS names start with "Cloud," such as CloudFront, CloudSearch, CloudHSM, CloudTrail, and Cloud9, all of which are extremely messy.

CloudWatch is an essential component of almost all AWS-based solutions.

CloudWatch Logs Service

AWS Cloudwatch Logs has been a fundamental, all-encompassing logging solution for your apps and services. Log data storage, retention rules, and basic management are all possible.

The main benefit of CloudWatch Logs is its centralized log storage and capture repository. For emitting log data, AWS services use CloudWatch Logs. Having a reliable access point and collection point for log data is quite beneficial. Numerous AWS services produce log information that is transferred to CloudWatch Logs for archival purposes.

Applications can receive CloudWatch Logs directly through the AWS API and CLI or indirectly through the EC2 CloudWatch Agent. Numerous logging frameworks include plugins that enable sending logs simply without scripting.

CloudWatch logs allow you to stream logs to other processing targets, such as Lambda functions and AWS ElasticSearch.

CloudWatch Logs has an essential viewer and query ability, but they are not the best. Most users supplement them with third-party logging solutions that ingest CloudWatch Logs data to provide enhanced visualizations and analysis tools.

Log Data

CloudWatch Logs ingests log data as a timestamped message. The message can be written in plain text, JSON, or any other format you prefer. CloudWatch Logs is unfamiliar with the format of log messages, so it generally accepts the message as written text.

Logs can be accessed and stored via a two-level hierarchy of named streams and log groups. These files and folders can be referred to as file system folders. Logs can be accessed only from a specific region. They are stored in the AWS region where they were captured and can be accessed through that region. It is not possible to view a log globally from all regions.

A log (or group) can specify a retention period after which events will not be removed from that log group. It is standard not to expire events. This can be expensive, especially when logs are scattered across the globe in different AWS regions. This can be problematic for CloudFront logs as they grow rapidly and are stored in the AWS region closest to the point of presence.

CloudWatch Logs Viewer

Top CloudWatch developers offer a straightforward log reader. One page of log events can be examined for each log stream at once. You must manually select a stream to be displayed if you want to only show a subset of the log event data. For several of its services, AWS regularly develops new streams. Lambda functions that execute cold starts result in the creation of a fresh log stream.

For embedded JSON strings, log data is shown as a timestamp, message, and attractive styling. At a specific moment, log data is rendered on a page. You can scroll, but you'll have to wait before the next page appears. Using the text filter in the viewer to filter log data using straightforward text patterns.

You can also use the date selector to set a range of dates. The viewer does not have a "live tail" option to display the most recent log events.

The viewer can't automatically combine events from different streams within a group. To display the desired log events, you must inspect each stream individually.

These CloudWatch Logs limitations can be frustrating when debugging apps using log data. To speed up your log browsing and analysis, you might consider using a faster CloudWatch logs viewer, such as the log viewer.

CloudWatch Logs Insights

Insights allow you to visualize and analyze log data using interactive query tools. Queries can filter and aggregate log data to create time series graphs to visualize log data or publish them to CloudWatch dashboards. Insights, a new addition to CloudWatch Logs (delivered in late 2018), is an interactive tool that allows you to filter and aggregate log data.

CloudWatch Metrics Service

CloudWatch's metrics service is composed of the following:

  • Metrics gathered from AWS services, CloudWatch logs Insights, and user applications
  • Dashboards that display time-series metric data
  • Alarms are triggered when metric values change
  • As metric values change, streams of events are generated

Metrics

CloudWatch metrics are time-ordered data points published to CloudWatch via AWS services, CloudWatch logs insights, or user applications. The metrics include a name, name, time, namespace, and zero or more key/value pair data.

AWS provides metrics for many services, including EC2, EBS, and RDS. These metrics show error conditions and performance rates. EC2 offers basic metrics free of charge with the option to monitor more closely.

Dashboards and graphs

AWS CloudWatch dashboards can be customized to allow you to monitor all your resources from one location. A dashboard can include multiple graphs or alarms and aggregate metrics from multiple AWS regions.

Multiple dashboards can be created for different views in your AWS account.

CloudWatch Alarms

CloudWatch Alarms monitor CloudWatch metrics continuously and alert when they exceed certain thresholds. An alert can be sent to the AWS Simple Notice Service (SNS) and implemented simple EC2 or AutoScaling actions. Alerts cannot yet be sent directly to Lambda functions.

CloudWatch dashboards can display alarm status.

CloudWatch Events

CloudWatch Events listens to AWS state changes and generates an event stream routed to the targets for processing. Events can be used to notify targets of state changes in real-time without needing to poll. Examples of events are an EC2 instance being terminated or launched, an AutoScale operation, or an RDS failover. Examples of targets are Lambda functions or SNS topics.

Rules that match event patterns with change signatures are used to filter out state changes. After filtering, an event is routed to the target as a stream.

CloudWatch developers can also generate scheduled events. This allows you to run Lambda functions, such as Lambda functions, according to a set schedule.
