If you’ve decided it’s time to Cloud-power your development pipeline with a transition to Serverless apps, you’ll need access to experienced Serverless application developers. Voilà! You need look no further than Munich-based Krusche & Company.
Serverless application development is a trend we, at K&C, believe is here to stay and represents the future of web development. Standardisation and re-use of common application components just makes sense. Every other kind of engineering standardises as many components as possible.
Why? Simple. Using standardised components removes much of the room for error and leads to better, more reliable products. As a result, Serverless application development also takes less time and is cheaper.
Despite the development and maintenance efficiencies the Serverless technology stack represents, developers do still need to learn new skills. Serverless architecture has its specifics. Components have to be configured correctly. And because each of the major Cloud vendors has their own native versions of components, neutralising the risk of vendor lock-in also means the architecture of an app should allow for these to be conveniently switched in and out.
Serverless application developers also have to be much more aware of the business case of the software they are building. The pricing model of Cloud vendors should be taken into consideration from the beginning of an application’s design so that the resources it uses, which dictate running costs, are optimised.
Regardless of whether you are exploring the option of Serverless apps, have already decided Serverless is the direction you want to take for a project or have a more specific bottleneck or need such as debugging AWS Lambda functions or Serverless for Big Data in AI please do get in touch. Our teams of Serverless application developers and consulting service will be delighted to help.
Whether it is an initial assessment of whether Serverless is the way to go for a project, assisting your in-house development team with experienced Serverless know-how or building out an application project in its entirety, let’s talk. Just drop us an enquiry online or pick up the phone. The first step to improving your next application is that easy!
Cloud applications were the natural evolution from traditional web development. Computing resource as a utility – scalable, flexible, pay-as-you-go. Serverless applications represent a further evolution of Cloud development.
Building apps in the Cloud involves combining SaaS and managed/Serverless services into fantastic solutions. Developing in this way is much faster and cheaper than the custom coding of A to Z traditional development involved. But combining all of these services into a smoothly functioning whole is still complex and involves time consuming manual work. And manual development work always increases the chances of inefficiencies and bugs.
Serverless application development takes things one step further than microservices-based Cloud development by introducing ‘components’. Serverless components are like Lego or Meccano pieces – standardised blocks or elements that are put together in different combinations to build unique applications.
Serverless architecture can be compared to mechanical engineering. A mechanical engineer will use standardised components for as much as possible and only ever use a unique, customised element when there is no other choice? It makes it much faster and cheaper to build something or repair it and a new engineer brought in will already have experience these elements.
Serverless app developers take the same approach. Apps, regardless of what they are for, have many common functionalities. Things like:
User management (sign up, create profile, be given access to a, b but not c feature etc.).
Image Processing API
The above are just a few examples. Cloud vendors such as AWS, Azure and Google Cloud offer ready components for all of these common app functionalities. The Serverless app developer plugs them into the right place and configure any variable settings. There will inevitable be custom coding required as well but, like the mechanical engineer, the Serverless app developer will consider that the last resort.
It sounds like a bit of contradiction in logic but while Serverless app development is easier than both traditional and cloud development the fact that it is such a paradigm shift in the development approach means there are difficulties in getting to grips with it.
Developers new to Serverless have many questions around how to best adapt existing practices within the new architecture environment.
Some examples might be:
Which language to choose? This will affect memory settings.
How much memory/CPU does a Serverless function require?
When should API functions timeout?
Which deployment framework to select?
The fact that Serverless components must be native to the Cloud vendor your app will run on often leads to inexperienced Serverless application developers locking their employer or client into a single vendor. If a Serverless app is built using AWS components and its owner subsequently wants to migrate to Google Cloud, this can be a massive headache. Particularly for large applications.
Experienced Serverless application developers have already felt that pain. Or been taught by someone else it has. They will build the app’s Serverless architecture in a way that neutralises vendor lock-in as much as possible. That can be achieved through the open source or enterprise Serverless framework.
A few of the questions around Serverless and the specifics of Serverless application developers we hear most often:
Communication: the number one issue when working with third party partners providing any kind of professional service is unsatisfactory communication. At K&C we believe that technical expertise should be a given for any outsourcer of IT services. Where we make sure we stand apart from our peers is the way that we work with our partners. And that is cornered on clear, regular communication and response times.
Technical Skills and Experience: developers who have worked on a wide variety of different projects will always have more experience than even the most competent of developers to have spent a long time working on one or a limited selection of applications.
Our Serverless application developers have all worked on many projects and that experience is invaluable when it comes to building yours most efficiently. We already have a knowledge and experience bank that is leveraged to your benefit. Whatever problem arises or challenge needs an answer, the chances are we’ve seen and dealt with the same, or a similar, issue before.
Optimised Model: with our Munich head office and nearshored offices in Kiev, Krakow and Sofia, Krusche & Company represents the perfect blend of German management and processes with tech talent at an affordable price point. We invest significantly in continuous education and training for all of our development talent, ensuring they are constantly pushed to develop and remain at the cutting edge of the quickly evolving technology trends that characterise our industry.
Affordable and reliable quality is our mantra.
Cloud Vendor Neutral: we never restrict ourselves to a focus or tie-up with any single Cloud vendor. We have deep experience with all of the major vendors, from AWS to Google Cloud, Azure, Oracle and more. But our policy is to remain neutral so we will always be able to provide an objective opinion on which best suits our partners’ needs.
If the advantages of Serverless compared to microservices and monolith architectures were to be summed up in as concise a way as possible, we’d describe them as:
Server management and maintenance taken off the table.
Pay-per-use pricing model further optimised from broader Cloud app development.
Provides for next level developer agility.
Security and redundancy levels democratised as Enterprise-grade.
Repeatable, code-defined infrastructure.
Container-based isolation, portability, and scalability.
We are surprisingly often asked if Serverless is a suitable choice for 'enterprise' or 'enterprise-level' apps.
The first point to make is that what size of organisation is building the app is irrelevant to the tech stack and choice of architecture. That is entirely down to waying up the strengths and weaknesses of different architecture options in terms of flexibility, budget and expected levels of usage/load.
It is certainly the case that a Serverless architecture solution can become more expensive than microservices if load volumes are particularly high. But only at the end of the scale that is inhabited by apps with particularly heavy loads. The beauty of Serverless is that it is much cheaper until that point.
This means demand for an app can be established at an efficient budget as well as changes and updates being easier and cheaper to make than is the case with non-Serverless architectures.
