An Introduction to Serverless
Serverless Architecture has been around for a while; AWS lambda or Google Cloud functions might be two you have heard of. If you haven't heard of those, then it might surprise you to know that NextJS and Gatsby (two of the most popular frontend frameworks today) both use AWS Lambda functions under the hood to execute the API responses when deployed.
Serverless Architecture has grown more popular as businesses started to realise how good of a choice it was for their companies and developers a like. In this blog post, we'll explain what serverless architecture is and look at some of the ways it can help businesses.
At its core, serverless architecture is a way to build and run applications without having to buy, rent, or source traditional servers. Instead of caring for infrastructure, developers write code that runs when certain events or triggers happen. These events could be anything from a user clicking a button on a website to a sensor noticing a change in temperature. Serverless architecture lets developers focus on breaking down their apps into simpler functions that execute individually instead of building the infrastructure they need to run them.
Cost savings is one of the best things about serverless architecture for business owners. With traditional infrastructure, businesses have to pay for servers and other hardware even when they aren't being used. With serverless architecture, businesses only pay for the computing resources they use. This pay-per-use model can save a lot of money, for small businesses or startups with intermittent traffic expectations, this is particularly useful.
Scalability is another great thing about serverless architecture. When traffic suddenly goes up on an application with traditional infrastructure, it can be hard and take a long time to add more servers to handle the load. Scaling is automatic and happens right away with serverless architecture. When demand goes up, the system automatically starts up new instances of the application and shuts them down when traffic goes back to normal.
Having no servers saves money
When cost reduction is paramount, and budget constraints are tight, Serverless can be the answer. With traditional infrastructure, businesses have to buy and take care of physical servers, even if they aren't being used to their full potential.
Businesses only pay for the computing resources they use with serverless architecture. Serverless architecture uses a pay-per-use billing model, which means that businesses only pay for the time their code runs. This can save a lot of money, especially for applications with fluctuating workloads or peaks in use.
Serverless architecture can also help reduce development costs by letting developers focus on writing code instead of managing infrastructure. Because serverless providers take care of the underlying infrastructure, developers can spend more time working on the actual application and less time managing servers and other hardware.
Serverless architecture also saves money because it gets rid of the need for expensive maintenance and upgrades. With traditional infrastructure, businesses need to hire IT staff to maintain and upgrade servers, which can be expensive. With serverless architecture, on the other hand, maintenance and upgrades are taken care of by the provider. This lets businesses focus on what they do best.
In conclusion, serverless architecture can help businesses save a lot of money by getting rid of the need for physical servers, lowering the costs of maintenance and upgrades, and letting developers work more efficiently. The pay-per-use billing model makes sure that businesses only pay for the computing resources they use. This makes it a good choice for businesses that want to cut costs and work more efficiently.
Serverless makes it easy to grow.
Another important benefit of serverless architecture is that it is easy to scale. With traditional infrastructure, businesses have to figure out how many servers they will need and buy them accordingly. This can cause resources to not be used enough or to be used too much, which can be expensive and wasteful.
On the other hand, serverless architecture is made to scale on its own. It can give resources to an application based on how much work it is actually doing, rather than a fixed amount. This means that businesses don't have to worry about not having enough resources or having too many. When traffic goes up, the system automatically scales up the resources to meet the demand. When traffic goes down, the system scales the resources back down to meet the demand.
This scalability feature of serverless architecture can be especially helpful for businesses that have traffic spikes that come on quickly or are hard to predict. For example, if a business puts on an event or runs a marketing campaign, it may see a big jump in the number of people who visit. With old infrastructure, businesses would have to buy more servers or upgrade the ones they already have to handle the extra traffic. With serverless architecture, on the other hand, the system automatically scales up the resources to make sure the application can handle the increased load without any human help.
Another benefit of serverless architecture's ability to grow is that it can help improve an app's overall performance. When an application is given more resources, it can handle more requests at once. This makes response times faster and the user experience better.
In conclusion, serverless architecture gives businesses the ability to automatically scale and deal with sudden spikes in traffic without having to do anything by hand. This can lead to better performance, a better experience for users, and lower costs related to over-provisioning.
How does Serverless make things safer?
When making and releasing apps, security is one of the most important things for businesses to think about. Traditional infrastructure doesn't have as many security benefits as serverless architecture.
Serverless architecture improves security in a number of ways, but one of the most important ones is by making the attack surface smaller. With traditional infrastructure, businesses have to manage and protect many servers, each of which could be used by an attacker to get into the business. With serverless architecture, however, businesses don't have to worry about managing servers or other hardware. Instead, the serverless provider is in charge of making sure the infrastructure is safe. This makes it harder for attackers to break into the application because it makes it harder for them to find places to attack.
Serverless architecture is also better for security because it can work with other security measures. For example, serverless architecture makes it easy to add another layer of security with multi-factor authentication. Also, serverless architecture can be set up so that only certain resources or functions can be used. This gives you more control over who can see sensitive information.
Lastly, businesses can get automatic security updates and patches with serverless architecture. With traditional infrastructure, businesses have to manage and apply security updates and patches to multiple servers. With serverless architecture, on the other hand, it is the provider's job to apply security updates and patches to the infrastructure underneath. This makes sure that businesses always have the most up-to-date security measures in place without having to do anything by hand.
In short, serverless architecture improves the security of a business by reducing the area that can be attacked, integrating with other security measures, and making security updates and patches happen automatically. With these features, businesses can make sure that their apps are secure and safe from possible threats.
Severless makes it easy and quick to build things.
Flexibility and speed are critical factors for businesses that need to develop and deploy applications quickly and efficiently. In these areas, serverless architecture has a number of benefits.
One of the best things about serverless architecture is that it can be changed easily. Since developers only need to focus on writing code, they have more freedom to choose the programming language and framework that best fits their needs. This can help development go faster and save money on costs related to learning new languages or frameworks.
Serverless architecture also lets apps be built and put into use more quickly. Businesses with traditional infrastructure have to set up and manage servers, which can take time and slow down development. With serverless architecture, on the other hand, the infrastructure is taken care of by the service provider, so developers only have to worry about writing code. This can speed up development and deployment, shortening the time it takes to get a product on the market.
Event-driven apps are another way that serverless architecture can make things more flexible. Businesses with traditional infrastructure have to set up servers to handle requests. With serverless architecture, however, applications can be made to respond to specific events, such as a user uploading a file or a sensor detecting a change in temperature. This can help businesses make apps that are more flexible and responsive and better fit their needs.
In conclusion, serverless architecture gives businesses the freedom to choose the programming language and framework that works best for them. It also makes it faster to develop and deploy apps. Event-driven applications can also be made to respond to specific events. This makes them more dynamic and useful for businesses.
