The rise of a new buzzword has made many people think that servers no longer exist, but the fact is, a server is still needed somewhere. This is why the “serverless” term may mislead many people. What makes “serverless” term is that you can successfully build your applications without deploying code to your own servers. Therefore, as a web developer your dream of spending less time worrying about servers and more time for building software will come true.

Serverless in Action

When your site serves many readers a month, it means that the traffic that comes to our scale is significant and sudden, as articles can go viral at any moment. As a result, you may have trouble keeping up and our engineers are spending too much time on operations. Therefore, as a solution, you can take a look at serverless platforms which offer you a complete success of your projects, such as more maintainable, easier to operate, and cheaper.

Amazon Web Services

Serverless has a close relationship with Amazon Web Services (AWS). In fact, AWS is the answer for one critical question; where does the custom code go? The concept of using third-party services and platform is not new, with database, you can push notifications, caching, and many other layers of an application have all been available ‘as a service’ for a while, but they sat on the edge of your application. Therefore, a server is still needed as a place for core application code, which is usually a server responding to external requests. Through AWS Lambda and AWS API Gateway, you can deploy custom application code without the overhead of managing your own servers.

AWS Lambda

Applying Lambda is quite simple, you only need to write code and upload it. Lambda is Amazon’s version of functions-as-a-service (FaaS). Then, as a response to events including HTTP requests, S3 uploads, DynamoDB updates, Kinesis streams, and many others, AWS will run the code. Since scaling happens automatically, you are only charged when your functions are running.

None of these features are strictly a requirement for serverless, but AWS has certainly set the bar high. Any serverless platform will likely to have a stateless FaaS offering with very granular billing because of the precedent set by AWS.

Other Platforms

Right now, Amazon may still be the first competitor in the arena, but other providers are showing up quickly. All the major cloud platforms have recently launched services targeted at serverless applications. Here are a few of them:

Google Cloud Functions: Still in alpha, having almost the same functionality to AWS Lambda and can also be triggered by HTTP requests.
Azure Functions: This platform is still relatively new and similar to Lambda. Other benefits are Azure has a pleasant UI and makes it easy to expose functions over HTTP without needing a separate routing service.
IBM OpenWhisk: This is the only open source platform. You will want to investigate this, if you are interested in deploying your own serverless platform or just curious with how they work under the hood.

Challenges

If you think serverless is the solution of every problem, you might be wrong, for serverless does not come without its challenges. In fact, the community is still discovering best practices, especially when it comes to operations as the space is new and as such. In fact, this platform still requires tools for deploying, maintaining and monitoring our applications. However, many believe that there will be many new startups’ third party services targeted at solving these problems for serverless developers.

Tools

With lots of open source community, it is possible to manually build and deploy serverless applications yourself, but we suggest that you use the existed frameworks, since a few endpoints, building, packaging, zipping, uploading and versioning all become difficult to manage. Here are some frameworks that you might want to consider:

Serverless framework: This framework has a robust plugin system and integrates with many community developed plugins with many community developed plugins. Its stated goal is to eventually support deployment to any of the major cloud platforms.
Apex: Even though it is written in Go, it supports Python, Node.js and Java runtime languages. Furthermore, the inventor of this tool, TJ Holowaychuk, is a well-known fixture in the open source community and has a great sense of what makes for good developer tools.
Chalice: it is the only framework created and maintained by AWS and currently supports Python.
Shep: If you are looking for framework that can be used for all our production services, Bustles’ own open source framework can be a great choice. It focuses on the Node.js runtime and strives to be opinionated about how you should structure, build, and deploy applications.

It seems that in 2017 “serverless” technology will keep growing and you will see rapid adoption from startups to fortune 500 companies. This is because many developers have realized that the serverless movement is the best way to build better software.

When creating compelling and engaging digital interfaces, web designers may apply a number of techniques, approaches and philosophies. In fact, each designer has their own preferences – some prefer to work from the top down, starting with the most basic elements and building their product down to the last detail. The atomic web design is common and often yields a well-thought out, quality product.

Why Atomic Design?

The bottom-up process is known as atomic design since it was influenced by chemistry. Here are the reasons:

Just like atom in chemistry, Atom in design is the most basic building block. Therefore, they can’t be broken down anymore without losing the essence of what they truly are.
To make the atom become functional; you need to combine two or more atoms together.
When molecules are combined together in a meaningful way, they become organisms – living, tangible forms.

The atom characteristics’ above show that there are so many similarities between atom in chemistry and atom in design, it holds that even the most basic HTML elements can be combined to create something tangible and functional. However, you may require a bottom-down approach to put it together

Furthermore, to ensure your user experience, you can ensure its quality in user experience.

The benefits of Atomic Design

Even though Atomic design needs a lot of thoughts and planning, you will find that the result is worth the extra effort. Below are some of the benefits of using this type of design.

Build a System of Components

Since you have broken a system down to its most basic parts (atoms), you can discover which parts that can be reused and how you can mix and match them to obtain more molecules and organisms.

More Intuitive Layout

By using atomic web design, interfaces tend to be more intuitive and easier to code. Besides, it is also easier for a new developer to understand the codebase, and it can minimize the risk of writing duplicate code. It’s easier to see where you’re using different components of a site, since you’re using “atoms to create the initial layout. To replicate existing code on the site, you can find it where it’s stored.

Your Style Guide is Simple

If you design a site according to the principles of atomic design, you can incorporate all your atoms and molecules into your style-guide. In fact, by this way, you can keep your design and messaging consistent across platforms. Even though you can extrapolate elements from a design that’s not atomic, it’s always better to begin with atomic design principles than to try and apply them retroactively.

Faster Prototyping and Updating

It’s easier to mockup pages and prototypes when you have a list of atoms on hand from the beginning. All you have to do is to combine your basic elements for the page. After that, you can refine and customize for the final site. Atomic design also facilitates quick updates and removal of certain design features. However, it is easier to ensure that your updates get carried out throughout the interface, when you’re only changing one element at a time.

By applying the atomic design, you will build a strong user experience (UX) structure through providing a methodology for designers. Furthermore, atomic design can also adhering to component-based guidelines, therefore designers can still rely on their creativity without clashing with developers.
