Amazon Web Services, popularly known as AWS in the market, is a secure cloud service platform. It offers various functions for a business to scale up and grow such as computing power, content delivery, database storage and many other functionalities.
AWS is a good career move for those who want to explore and grow in the field of cloud computing. With the help of AWS, an individual, company, enterprises can get a cloud computing platform. For starting a career in AWS as a fresher, first of all, you need to undergo training for AWS.
Yes, you can get a job even when you are an AWS fresher. But make sure you know all about AWS Cloud. However, only learning about the AWS cloud is not enough to get your hands on a good job.
We are happy and proud to say that we have strong relationship with over 700+ small, mid-sized and MNCs. Many of these companies have openings for AWS. Moreover, we have a very active placement cell that provides 100% placement assistance to our students. The cell also contributes by training students in mock interviews and discussions even after the course completion.
AWS is primarily an Infrastructure as a Service (IaaS) Cloud Platform. You need not know any programming to be successful in AWS “mostly”. However, all of that depends on exact role you get into. If you are writing scripts/programs for automation/control of AWS services, programming knowledge is a must.
- Having basic knowledge of operating systems like Windows OS, Linux etc
- As Visualization play a major role in AWS you need to have the understanding of it
- Networking is an essential skill as all operations on cloud platform involves it.
- Understanding the difference between the Public and Private cloud
- Last but not the least, you must have basic command over coding
- Amazon Web Services (AWS), Python or C# Most architects have a software development background.
- Networking.
- Data storage fundamentals.
- Security foundations.
- AWS service selection.
- Cloud-specific patterns and technologies.
- Communication.
Our courseware is designed to give a hands-on approach to the students in AWS. The course is made up of theoretical classes that teach the basics of each module followed by high-intensity practical sessions reflecting the current challenges and needs of the industry that will demand the students time and commitment.
The future of AWS is bright. Infact, it's the future of modern day computing. Cloud computing, machine learning, IOT, etc are some of the domains which have a lot to offer in the near future.
Depending on how much experience you already have, it’s possible to learn AWS in 3 days with our instructor-led courses comprising of 18 hours of training. If you’re looking to gain AWS certification this will take a little longer, as you’ll also need to prepare for the exam.
- Customization.
- Flexibility & Scalability.
- PaaS Offerings.
- Security.
- Scheduling.
- Recovery.
- Consistency.
- Global Architecture.
Amazon Simple Notification Service (SNS) is a highly available, durable, secure, fully managed messaging service that enables you to decouple microservices, distributed systems, and serverless applications.Some of it's features and benefits are listed below.
Amazon SNS features
Event sources and destinations
- Event-driven computing is a model in which subscriber services automatically perform work in response to events triggered by publisher services. This paradigm can be applied to automate workflows while decoupling the services that collectively and independently work to fulfil these workflows.
- Amazon SNS is an event-driven computing hub that has native integration with a wide variety of AWS event sources (including Amazon EC2, Amazon S3, and Amazon RDS) and AWS event destinations (including Amazon SQS, and Lambda).
Message filtering
- Message filtering empowers the subscriber to create a filter policy, so that it only gets the notifications it is interested in, as opposed to receiving every single message posted to the topic.
- Additionally, you may monitor your Amazon SNS message filtering activity with Amazon CloudWatch and manage Amazon SNS filter policies with AWS CloudFormation.
Message fanout
Message fanout occurs when a message is sent to a topic and then replicated and pushed to multiple endpoints. Fanout provides asynchronous event notifications, which in turn allows for parallel processing.
Message durability
Amazon SNS uses cross availability zone message storage to provide high message durability. All messages published are stored redundantly across multiple geographically-separated servers and data centers. In case the subscribed endpoint isn't available, Amazon SNS executes a message delivery retry policy and can also move messages to dead-letter queues (DLQ). For more information, see Message Delivery Retries and Amazon SNS Dead-Letter Queues.
Message encryption
- Amazon SNS provides encrypted topics to protect your messages from unauthorized and anonymous access. When you publish messages to encrypted topics, Amazon SNS immediately encrypts your messages.
- The encryption takes place on the server, and a customer master key (CMK) issued with AWS Key Management Service (KMS).
- The messages are stored in encrypted form, and decrypted as they are delivered to subscribing endpoints (Amazon SQS queues, AWS Lambda functions, HTTP/S ).
Message privacy
- Amazon SNS supports VPC Endpoints (VPCE). You can use VPC Endpoints to privately publish messages to Amazon SNS topics, from an Amazon Virtual Private Cloud (VPC), without traversing the public internet. This feature brings additional security, helps promote data privacy, and aligns with assurance programs.
- When you use AWS PrivateLink, you don’t need to set up an Internet Gateway (IGW), Network Address Translation (NAT) device, or Virtual Private Network (VPN) connection. You don’t need to use public IP addresses, either.
Benefits of SNS
Instantaneous delivery
SNS is based on push-based delivery. This is the key difference between SNS and SQS. SNS is pushed once you publish the message in a topic and the message is delivered to multiple subscribers.
Flexible
SNS supports multiple endpoint types. Multiple endpoint types can receive the message over multiple transport protocols such as email, SMS, Lambda, Amazon SQS, HTTP, etc.
Inexpensive
SNS service is quite inexpensive as it is based on pay-as-you-go model, i.e., you need to pay only when you are using the resources with no up-front costs.
Ease of use
SNS service is very simple to use as Web-based AWS Management Console offers the simplicity of the point-and-click interface.
Simple Architecture
SNS is used to simplify the messaging architecture by offloading the message filtering logic from the subscribers and message routing logic from the publishers. Instead of receiving all the messages from the topic, SNS sends the message to subscriber-only of their interest.
