FaaS v/s Serverless

This is a time when trends are changing. Enterprises have changed the way they used to approach a lot of things. There are no print or TV advertisements now, everything is digital so they are now moving to digital marketing. Having an application made for themselves is sometimes too costly and may not work in their favor. This is the reason why they are shifting towards the cloud. Cloud is not the actual cloud which creates thunder and produces rains, but the ones where we can work, where we can host various services. There are two services which are the main focus of this article, they are Serverless and FaaS i.e., Function as a Service. This article will show how they are similar and what are the differences between them and which one of them is better.


FaaS Function as a Service

FaaS can be extended as Function-as-a-service. It falls into the category of cloud computing services which are disrupting the process of building applications and systems. In FaaS, the server-side logic remains the responsibility of the app developer as it is happening in conventional architectures. But on the other hand, the server-side logic runs in compute containers which are stateless. These containers can be triggered by one event which often lasts only for one innovation.

These kinds of events are fully handled and monitored by third-party vendors. There are many FaaS options used all over the world including AWS Lambda, Google Cloud Functions, Microsoft Azure Functions. The list extends to many open source options too such as Oracle and IBM. Similar to other services, FaaS is a third party platform. The user only has to pay for it when they use it. It is highly cost-efficient to use. This platform enables the developers to focus on the design, management as well as running of application functionalities.

  • Advantages:
    • The developers and the enterprises don’t have to write an entire application code if they want to complete a small task.
    • This is very cheap. In FaaS the code is in small pieces and they run only when they are triggered. The users only have to pay when they use it. There is no continuous or fixed cost.
    • In respect to demand, the developers can increase the speed and easily build and copy a function rather than copying the whole application.
    • It is also easy to scale a function rather than scaling an entire application when the demand increases. Hence, we can say that FaaS is also highly scalable.
  • Disadvantages:          
    • The functions can complete only one task and they are very small.
    • There are so many functions sometimes and managing all of them becomes a tricky task.


This is quite tricky to explain. There is much meaning of the word itself even if it is not properly explained. Some people might think that it is something which runs without any server. If we look at it practically, it is impossible. It is really necessary to understand what it is and why it is used? As far as this article is considered, it is told that it is a cloud computing service. That is not so much information, to be honest. Serverless in its best sense can be understood as something which is not in sight. Still, there is not much specification about it which relates it to cloud computing. Let us understand this in detail.

If we take traditional computers, they work on a server, this central server is responsible for the management of activities like flows, controls, and the security of the device. Now, talking about the new modern age serverless version of these. There is no central authority which helps the machine in balancing different branches of a device. The serverless model makes the device or the network more efficient as in it all the parts of the device or the server are self-aware and they do their own task as individuals. These applications are more flexible and can adapt to a change in a better way with respect to other types of applications. This is one of the important reasons why most of the modern-day businesses choose them.

There are two ways in which the applications are divided into. Serverless is one of them and SaaS is another. Serverless also intersects with SaaS at some points but both of them have a lot of distinct features. That should be clear till now because they are explained above. The first type has applications which make use of third-party applications and services hosted on the cloud. These are used to manage the logic and state at the server-side. The application of this type mostly uses a big ecosystem of databases and authentication functions that are based on the cloud. They are also known as Backend as a Service or BaaS.

Let us know about some advantages and disadvantages of serverless technology:

  • Advantages:
    • Users don’t need to configure the server at the time when they deploy the application.
    • These are most of the time very easy to use and provide better performance than other apps. These are also easy to scale.
    • They offer more flexibility than other types of applications.
    • It is cheaper than the traditional server-based method of hosting. The reason behind this is the flexibility of the platform.
  • Disadvantages:
    • One big loss is that the users might lose control to some extent. It is said that this type of computing is the loss of server control. If the user decides to choose this option then they have to give up the option of controlling the server. Otherwise, if they wish to control the server, they will have to allow some specifications in the server to be changed.
    • There are some cases when this type of server hosting is more expensive than traditional ones. The number of calls being made is also very much. There are some situations in which the API has to be used extensively and in those situations, the price is more.

Which Is The Better One?

Back to the main question from where it all started. After reading the whole article till now, we don’t think there is a need to choose between the two. Both of them might intersect with one another at some points but it is better to use them as per the need of the organization. This is not something that can be used anywhere. Even though both are cloud computing services there are some very different jobs which they can do and that should become the base while deciding. There are enterprises that need services that can help them build and replicate functions or maybe they will need some hosting server like serverless.

The decision that is made, it depends on the enterprise entirely. There is no other factor that can change it. The decision should be taken according to the need of the enterprise, there might be situations where an enterprise would need both. That is also correct in a way, they are both useful and when they are brought together, they can do wonders. Finally, just understand what they are in detail, know what are the demands of the enterprise and choose accordingly. Both of them are useful and both of them are best in their own way.

COVID-19 Prevention Measures

The world is going through the worst phase. No one ever thought that they would have to stay locked inside their homes. There is a war going outside and the only way to win this is, not to get involved in this and stay away. This is something that most people are not actually getting, they are not realizing the risk. They go out and they don’t only put their lives at risk but also become dangerous for everyone they meet after that.

The Current Global Situation

The governments of the countries are trying their level best to control the spread of this virus. Even after so many efforts, the virus is still spreading like wildfire. Italy, Spain and the USA are facing the worst in the world and everyone is praying that they don’t get where they are. The main reason why these countries are facing such bad conditions is their negligence towards the virus. Italy took it very lightly and at this point has the most number of dead people all over the world. There are many countries who locked their countries down totally after seeing the effect of the virus on the countries that took it lightly. India took the decision very soon and is still facing a few challenging conditions. India is still in better condition than other countries in the world and is following the total lockdown phase during this pandemic. By following some proper precautions and safety measures, we can save ourselves and our family from this deadly virus.

Important prevention measures to take during COVID-19

Prevention measures than can be taken to stop coronavirus and prevent it from spreading are as follows:

1. Cleaning hands at regular intervals

Cleaning hands at regular intervals

This is very important. The main reason how anyone can get this infection is through their hands and if they touch their face. We touch many things with our hands and no one knows what is clean and what carries the virus. It is important to wash hands at regular intervals with soap for at least 20 seconds. 20 seconds is the time which takes to completely disinfect the hands. If people are at a place where they don’t have soap and water then they can also use hand sanitizers.

Hand sanitizers are not needed when you are inside the home, they are only when you are out. By the way, it would be better if you can avoid going out in the first place for some days. It is important for everyone because a human might not get too affected but can affect some others badly. It is deadly for small kids and old citizens. Youngsters taking this lightly might become murderers of innocents if they don’t stop themselves.

2. Avoiding close contact

Avoiding close contact

It is advised to stay at least a meter away from even the family members. If going out to buy essentials then also keep a distance from other people standing there. No one is sure, the person standing next to in line might be the carrier of the virus and that is why it is better to stay away. Everyone needs to follow social distancing at this point in time. Even the doctors are saying this, social distancing is the best way to stop the spread of this virus. Stay inside your house, if fever and cough are the symptoms, isolate and wait for a medical assistant. Don’t meet anyone who is ill. There are people who are not following this and they might have to pay something that they will not be able to afford.

3. Covering mouth and nose

Covering mouth and nose

Whenever a person is going to meet someone it is better to cover the mouth and nose. It is not certain that everyone that a person will meet will be totally fit. There are chances that someone will sneeze and it is proven that this virus can travel to some distance in the form of water droplets. It is advised to keep a face mask handy and use N95 masks to stay safe. Covering mouth and nose is important mainly when the person knows that they are going to a place where the virus has already been found. If they are in a place which is safe from the virus then face masks are not mandatory.

4. Covering while coughing or sneezing

Covering while coughing or sneezing

This is something which people need to adapt to their life. While sneezing or coughing if they cover their mouth and nose with their hands they collect the germs in them. It is basic human nature that we touch our face with our hands when we feel even a bit of irritation. In the case of coronavirus, we might harm ourselves or might transfer them to anyone else. It is better to keep the virus away from hands as much as possible. Covering our nose and mouth with our elbow will make sure that it does not get transferred to anyone else.

5. Disinfecting and cleaning

Disinfecting and cleaning

It is extremely essential to clean and disinfect frequently touched surfaces. There are many surfaces at home, or in the workplace, which are touched by people the whole day. These may include tables, knobs of doors, light switches, countertops, handles, phones, laptops, keyboards, desks, toilets, faucets, sinks, taps and so on. Cleaning the surfaces with normal water may not disinfect it properly. In this scenario, common household disinfectants can work. Another option is to use bleach. By diluting the household bleach in a proper manner so that it does not damage the product as well as the user and the surfaces can be disinfected.

Frequent cleaning makes it tough for the virus to stay there for longer times. Users can also use cleaners which are alcohol-based and must have 70 percent alcohol in them. It is important to follow the instructions as well as other details of manufacturers such as concentration, application method, contact time and many more while using these cleaners.

Final Thoughts

This time is tough, but not inevitable. Through proper precautions and care, we can overcome this pandemic and be the heroes of the world. The most important thing right now is to be aware, positive and extremely careful. These simple steps can lead to restricted spreading and even elimination of the virus from the world.
