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 optimization.
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 optimization 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.
Amazon Elastic Compute Cloud (Amazon EC2) can be considered as a feature within the Amazon Web Services or AWS. A great feature of EC2 is that you do not have to invest in hardware. AWS EC2 helps you to develop and deploy your applications at a much faster rate. EC2 lets you launch as many servers as you want. These virtual servers can be many in number or very few. You can then do the configuration, manage security, storage etc. With EC2, managing traffic is also very easy. You no longer have to forecast the frequency of the traffic. It can automatically make the required changes to manage the sudden spike or reduction in traffic. There are many features of AWS EC2 that help it to put forward applications that are scalable and resilient.
Access to the underlying server is one very great advantage provided by EC2. The EC2 bare metal instances gives your application a direct access to the processor and memory of the server. These are particularly useful when you have workload that require access to memory.
Pause and Play
Bare metal instances are one of the instances offered by EC2 and functions just like their other instances. Another great feature is that these instances can be stopped and then resumed later. Applications that persist and take time to get into the memory can be benefited with this feature. In addition, you will not be charged for the instance that has been paused or hibernated.
Types of Storage
Dense storage features are also very beneficial to customers. If they require high-intensity storage applications, then this instance will come in handy. Storage is another great benefit or service offered by AWS EC2. Different workloads will have different requirements for storage. AWS EC2 can accommodate these different needs. In addition to a storage capacity that is built in, they have also considered other provisions for storage. These are Amazon Elastic Block Store, Elastic File System etc.
Control and Optimisation
There is also another feature that lets you control the instances. These are called the optimise CPUs which give you the control over the instances over both the fronts. This helps you to save on a lot of CPU based licensing costs. Some customers look for greater graphic experiences. GPU graphic instances are perfect for this.
Pay Per Use
Pay per use is one of the greatest ever modifications that they brought about. Even though some instances might start booting, they might not really start immediately. You will be charged according to the actual time it starts. You will only be paying for the resources that you use. Many idle resources will not be included.
An elastic IP address is also a great feature. These are static. They are designed for better cloud computing experience. You also have greater control over this IP address, which is connected to your account and you can control it until you release it.
