If your workload requires a small computer power, let us Read more…
6. What is Amazon DynamoDB?
DynamoDB is a database service that is provided by amazon web services (AWS). DynamoDB is also known as the NoSQL database where we make use of JSON queries to work with the database, unlike SQL database where we use SQL related queries to work with the database. This database is very flexible as well as fast and is used for applications that have the necessity for consistency and latency at the rate of a millisecond at any scale. Read More…
7. What is Amazon Relational Database Services?
The essential structure square of Amazon RDS is the DB case. A DB occurrence is a separate database condition in the cloud. A DB occasion can contain different client made databases, and you can get to it by utilizing similar instruments and applications that you use with an independent database example. You can make and alter a DB occasion by utilizing the AWS Command Line Interface, the Amazon RDS API, or the AWS Management Console.
The calculation and memory limit of a DB occasion is controlled by its DB example class. You can choose the DB case that best addresses your issues. On the off chance that your needs change after some time, you can change DB cases. For data, see Choosing the DB Instance Class.
It gives cost-proficient, resizable limit with regards to an industry-standard social database and oversees basic database organization undertakings.
Monitoring and Availability Zones
Amazon distributed computing assets are housed in profoundly accessible server farm offices in various zones of the world (for instance, North America, Europe, or Asia). Every datum focus area is known as a district.
You can run your DB occasion in a few Availability Zones, an alternative called a Multi-AZ organization. When you select this alternative, Amazon consequently arrangements and keeps up an optional backup DB occasion in an alternate Availability Zone. Your essential DB example is synchronously reproduced crosswise over Availability Zones to the auxiliary occurrence to give information excess, failover support, dispose of I/O solidifies, and limit inactivity spikes during framework reinforcements. For more data, see High Availability (Multi-AZ) for Amazon RDS.
A security gathering controls the entrance to a DB occasion. It does as such by enabling access to IP address extents or Amazon EC2 examples that you indicate. Amazon RDS utilizes DB security gatherings, VPC security gatherings, and EC2 security gatherings. In straightforward terms, a DB security gathering controls access to a DB example that isn’t in a VPC, a VPC security gathering controls access to a DB occasion inside a VPC, and an Amazon EC2 security gathering controls access to an EC2 case and can be utilized with a DB case. For more data about security gatherings, see Security in Amazon RDS.
Checking an Amazon RDS DB Instance
There are a few different ways that you can follow the presentation and wellbeing of a DB occurrence. You can utilize the free Amazon CloudWatch administration to screen the exhibition and strength of a DB occurrence; execution outlines are appeared in the Amazon RDS comfort. You can buy in to Amazon RDS occasions to be advised when changes happen with a DB example, DB Snapshot, DB parameter gathering, or DB security gathering. For more data, see Monitoring Amazon RDS.
Amazon RDS Interfaces
There are a few different ways that you can connect with Amazon RDS.
AWS Management Console
The AWS Management Console is a straightforward online UI. You can deal with your DB occasions from the reassure with no programming required. To get to the Amazon RDS support, sign in to the AWS Management Console and open the Amazon RDS.
Programming with Amazon RDS
On the off chance that you are a designer, you can get to the Amazon RDS automatically. For more data, see Amazon RDS Application Programming Interface Reference.
For application advancement, we prescribe that you use one of the AWS Software Development Kits. The AWS SDKs handle low-level subtleties, for example, confirmation, retry rationale, and mistake dealing with, so you can concentrate on your application rationale. AWS SDKs are accessible for a wide assortment of dialects. For more data, see Tools for Amazon Web Services .
AWS additionally gives libraries, test code, instructional exercises, and different assets to enable you to begin all the more effectively. For more data, see Sample Code and Libraries.
How you are charged for Amazon RDS
When you use Amazon RDS, you can use on-request DB cases or held DB occurrences. For more data, see DB Instance Billing for Amazon RDS .
8. AWS Elastic Load Balancer – ELB
Elastic Load Balancer distributes the incoming network traffic from application across different servers possibly could be different Availability Zones as well.
It helps and increases fault tolerance of your applications.
It serves a single point of contact for your clients ensuring that the application are available all the time.
You can either add of remove the instances from load balancer which does not affect your load balancer and so is the same deleting load balancer does not affect your Ec2’s.
It helps in scaling your load balancer’s traffic to your application as it keeps changing over time and also takes care of the majority of workload automatically as in when scaled.
Elastic load balancer has their own DNS names, they are never given any IP’s.
With DNS we can check how the load balancing activity takes place.
Health checks are mandatory to be set up on load balancers as they bring in the status of the load balancers.
It is basically the sanity checks that are tracked about the servers to report whether are healthy or unhealthy.
Main Health check responses set are:
Response time out:
When checking for an output it should bring in the status in scheduled time if no response it should at least throw the error message in allotted response time out.
Either an error or a response should be displayed in scheduled time.
The time taken to distribute load amongst the Instances.
Any output expected to be displayed within scheduled time also showing that servers are healthy enough to bring in the out managing the load.
If the instances are down or unresponsive or breached the threshold,load balancer will fail to manage the load.
Types of Elastic Load Balancing
Elastic Load Balancing supports three types of load balancers:
1.Classic Load Balancer.
2.Application Load Balancer.
3.Network Load Balancer.
Classic Load Balancer
Classic Load Balancer provides basic load balancing activity like any other load balancer across multiple EC2 instances.It works as per the Transport layer(4th layer) in OSI model.This was predominantly used before application load balancer was in place.
Application Load Balancers
Application Load Balancers works as per application layer(7th layer) of OSI model. Based on the application usage the loads are distributed and managed accordingly.
Network Load Balancer
Network Load Balancer is ideal for load balancing of TCP traffics. Targets could either be instances,containers,microservices etc.It can handle millions of requests per second at low latencies ensuring the network performance is high.
Key features in load balancer are:
- It ensures that high availability feature is in place, across multiple or single availability zone by distributing the incoming traffic.
- The request handling capacity is scaled up for in response to the incoming application traffics.
- Health check is one of the important features in ELB as it shows or brings in the status of servers. It ensures the sanity and status check of the servers.Ideally bringing in or detecting the health of Amazon EC2 instances.
- If any of the EC2 instances are found to be unhealthy,the load balancer routes the traffic to other servers rather than on the faulty or unhealthy servers or EC2 instances.
- Security features are enabled by adding security groups,NACL’s(Network Access control list) or even VPC(virtual private cloud) in load balancers.
- Load Balancer supports both IPv4 and IPv6 addresses
- Any metrics of load balancers are tracked by the monitoring or management tool called “Cloud Watch”.
- Logs retrieved from cloud watch for the same will help in diagnosing any application failures or web traffic..Load Balancer encryption is taken care by SSL secure socket layer) certificates, including public key authentication and offloading of SSL(secure socket layer) decryption from application instances.
- Load Balancing activity and Autoscaling services can be combined together to ensure the traffic’s are well managed and balanced ensuring the applications and services are in place.
