AWS (Amazon Web Services) is a cloud computing service that aids a computing infrastructure with a virtualisation environment, network, servers and hardware units. AWS has been started as an initiative to provide a virtualisation environment in addition to resource provisioning which is integrated and provided via online to the third party. It was initially started as an IAAS layer and later had a straight cut growth to Platform as a Service (Paas) which can provide complete assistance for project development with OS and middleware.
Lambda function has been used to attest a function with each datum so as to enhance its context as it transits from one state to another. Put in simple terms, we can scale our image to fit into the window display of smartphones or notebook in a responsive format.
AWS lambda is a serverless architecture that enables you to promote an application purely customised based on the needs of the end user on an event-driven computing platform. Earlier, serverless architectures were used to develop an application that was purely deprived of server-side state and logic.
Here we have an event trigger which is completely aided by Lambda function which provides the service FAAS i.e. Function as a Service, where we break down large monolithic applications to smaller services which are again disintegrated to the level of functions and events.
The prime merit of AWS Lambda is that managing and forwarding RPC calls to remote servers are completely avoided for enhancing computational time optimisation.
Lambda function works cooperatively with S3 (Simple Storage as a Service) where cumulative storage is possible.
If you build and manage your own FaaS infrastructure, it is all about optimisation of resources that trace back to reduce cost – a major reason to adopt serverless.
- Eager Development
Serverless architecture can be rapidly developed by product engineers. It has alleviated the problems of server crashes. Thus, it needs very less time on operational issues making developers life stress free.
- Operational Management Optimisation
Reduced computational cost and reduced operational management overheads are the added advantages of Automatic scaling functionality of FaaS. Serverless platform segregates the infrastructure services and applications running on top of the OS and middleware. Thus, a completely serverless solution like AWS Lambda will not require system administration.
- Reduction in Operational Costs
The basic merit of this technology is that you only pay for the time your function executes and not for standalone time and uses only resources on demand.
Holding a web-socket connection open for a chatbot for long is one menial task that cannot be done by AWS.
State-full service, which needs a connection-oriented service requires a database and is required to store any data that needs to remain consistent.
- DoS (Denial of Service)
AWS Lambda limits concurrency and jobs in the ready queue may be temporarily sidelined and can undergo starvation leading to deadlocks.
- Execution Duration
AWS Lambda functions are aborted if they run for longer than 5 minutes or a pre-set deadline. There are tasks that run for more than the given limit which may be left unexecuted.
We would like to ponder over your thoughts on serverless architecture and AWS Lambda.
aTeamIndia uses AWS Lambda as their serverless platform because they give importance to fulfilling all of their client’s demands. AWS Lambda is dynamic in the sense that it provides numerous services. Lambda makes it easier for you to run your code without having to worry about managing servers. It only executes the code when it is required and gets scaled automatically. They also have a pay per use scheme, according to which you only pay for the resources that you have used. This will help you save money and does not lead to a situation where resources are laid idle. A unique feature of Lambda is that you can run code for any type of backend service without any kind of administration. Lambda performs all the administration of computing resources and all that you have to do is make sure that the code is in a language which is supported by Lambda. Many companies run their applications and services on AWS Lambda as they found it to be more efficient than older methods. Because of its pay-as-you-go facility, it provides many cost-saving features. They provide IT resources that are on demand which in turn helps organisations to improve their agility. Using Lambda has also helped them reduce the time it takes for them to bring their product to the market. Lambda removes all the complexities and limitations while dealing with cloud-based servers making it the most convenient platform to use. It has the feature of scaling automatically and can handle few requests to a thousand requests a day. Only the server time that you utilise will be accounted for. Lambda also runs your code on an infrastructure that is highly available. For any service that you render, Lambda performs the responsibility of all the administration activities and functionalities. Also with Lambda, there is no idle server time and hence it’s never cold. Companies can directly benefit from the pay-per-use method. This is especially useful for startups that begin with limited or no capital as it decreases TCO or the Total Cost of Ownership. Functions like code deployment and security patching are taken care of. Lambda is also the most adaptable serverless application model. Any type of application can be applied to it. It can perform functions like managing the simple web application of a startup company to managing the trade analysis platform of a multinational company. Lambda makes it possible to not pay for anything when there is no traffic. Lambda enables it to handle excessive traffic as well.
Using AWS Lambda gives an extra edge to the services provided by aTeamIndia and has helped it to the path of success. They provide services of both web engineering and mobile engineering. Under web engineering, they provide services like Web Designing, Content Management System, Custom Web Applications, E-commerce Service, Web API Service, Framework Service, SEO / SEM, Live Telecasting Service. aTeamIndia is now a trusted software developing country across the country.
AWS or Amazon Web Services is a cloud computing platform that is comprehensive and ever-evolving. One of the major reasons that everyone uses AWS is that there is no long- term contract or any commitment. All AWS services and resources are billed on an hourly basis and can be stopped anytime. You only need to pay up to that hour and no more. Other servers and services require long-term commitments which are more difficult to commit due to a lot of constraints and scalable issues. Hire AWS developers if you are looking to upgrade your tech business to AWS. This is because AWS requires a certain range of expertise to handle its every aspect and only AWS experts can do it.
AWS is more of a pack of services and platforms. One of its popular services is the AWS Lambda which is a serverless event-driven platform. Yes, you heard it right. AWS Lambda is a serverless platform meaning that servers are not required to run it. It generates code specifically for responding to certain events and allocates resources required to run the said code. Similarly like AWS, Lambda also requires a certain degree of knowledge to execute it properly and you need an AWS Lambda team for that. So hire AWS Lamba expert if this is your groove.

Another awesome service that Amazon provides is the AWS S3 Storage. In today’s world, the size of data is increasing at a giant rate. So companies and AWS developers need the convenience to store large amounts of data easily in cloud. Like all products and services of Amazon, S3 storage also comes with top-notch security features to protect data as Amazon knows that it is very important to you. Protecting data is also equally important to Amazon. This is why Amazon provides S3 with three different forms of encryption. Like a bonus feature, Amazon allows one to analyse the stored data in cloud for in-depth data analysis.
The things mentioned above are just a few of the many valuable services provided by AWS. This is why you need a dedicated AWS team to know all these terms, their functionalities and contributions that it can make to take your technological business to the next level.

Amazon Web Services, a comprehensive evolving on-demand computing platform was launched in July 2002. AWS is basically crafted from the internal infrastructure that Amazon.com built to handle its online retail applications. Compute, storage, databases, analytics, and networking are some of the products provided by AWS. Products like mobile developer tools, management tools, IoT, security and enterprise applications are also provided. On a paid subscription basis, the service can be utilised by individuals, companies and governments. With the help of the services provided, organisations are pushed to move faster at lower IT costs and scale.
AWS is one of the first services to bring forth the idea of pay-as- you-go cloud computing model. It aids in providing the user with computing, storage or throughput as required. In addition to powering workloads of storage, warehousing, and archiving, AWS also powers web and mobile applications, game development and data processing. This wide variety of workloads are entrusted to AWS by large enterprises and rapidly developing start-ups.
The services of AWS are provided from dozens of data centres spread across availability zones (AZs) which is different from other technology infrastructure providers. Reliable, affordable, and cost-efficient cloud computing resources are provided by AWS to the customers. The ‘autoscaling’ tool of AWS provides scale capacity. This is to maintain instant health and performance of specific workload types and applications. Scalable object storage for data backup, archival and analytics is one major service offered by Amazon SimpleStorage Service (S3). But for long-term cold storage, Amazon Glacier is recommended.
Amazon Relational Database Service and a high-performance database called Aurora provides managed database services. As memory data caches for real-time applications, an AWS customer can use Amazon ElastiCache and Amazon DynamoDB. Data analytics can perform business intelligence tasks with the help of Amazon Redshift which offers a data warehouse. A location to monitor and manage migrations from premises to the cloud is provided by AWS Migration Hub. To get a control over a virtual network, an isolated sectionof the AWS cloud is used. In case of an IT specialist, it’s done via AWS Direct Connect. The development tools and application services are accessed through the services like AWS Command Line Interface, Amazon API Gateway, Amazon Elastic Transcoder, and much more.
