Cloud Computing

What is Cloud Computing?

Hosting your app in the cloud opens up a world of significant benefits.

Cloud-based technologies give you access to virtually unlimited storage space and bandwidth. This means you can scale up in real-time and save the time and resources required to buy and install equipment on-site. It’s also flexible because your employees can remotely access applications and data.

How is it better?

It’s faster. It’s cheaper. It saves time by moving beyond the old ways of having to design, re-architect, test, migrate, then ultimately deploy.

Self-hosting legacy platforms cost time and resources with maintenance and staying ahead. Moving to cloud hosting opens new options like delivering quick POCs (proof of concepts) while giving clients global access to your systems and apps — anytime, anywhere in the world. It also keeps you ahead of innovation as storing an app on a service provider’s servers means you get immediate access to innovative features and tools.

In addition, it aids productivity and performance with its on-demand scalability options and access to features, functions, and data. Beyond speed and flexibility, cloud hosting is also cost-effective, reliable, secure, and manageable.

What are microservices?

Microservices divide large software projects into smaller, independent modules. These modules communicate through simple APIs (Application Programming Interfaces). This means microservices perform better than monolith architecture because they are considerably faster for developing, testing, and modifying. Amazon, Netflix, and eBay are some innovative businesses taking advantage of this solution.

What makes microservices so attractive?

First, if there is a fault in a single module, it doesn’t affect the whole app. It also means you have the flexibility to experiment with a new technology stack on individual services, as and when you need to.

And because this involves less code and is much simpler, developers can understand and work with a service’s functionality. Smaller codebases also make it possible to achieve quicker deployments. Not to mention that separate, smaller, more manageable services mean it’s easier to scale necessary ones at the right time. Timesaving, money-saving, flexible.

Single-Page Applications

What are SPAs?

Single-page applications (SPAs) are becoming more popular. And while this is not the only route to take in modern web apps development, the benefits are definitely worth considering.

What are the benefits to SPAs?

First, SPAs allow for fast development and easier, effective maintenance. This is because developers can focus on a modular approach to software engineering. This also leads to faster load times, quicker development of new features, simpler ways to experiment with A/B testing, and cost savings with the potential to re-use code in other apps and products a company may need. Offline capabilities make applications used in critical environments more robust. Often this approach makes it a lot easier to create responsive websites that work for mobile, meaning businesses can get their apps to mobile without having to build a separate native application.

SPAs also mean opportunities for great UX, providing a clean, easy-to-use, linear user experience. And when comparing SPAs and multi-page apps, we have found that when executed properly, SPAs have better conversion rates.

Compatibility &

Compatibility &

Choosing modern web apps can keep you from common pitfalls that come with maintaining legacy systems. Things like incompatibilities with upgrades and becoming more vulnerable to bugs and cyberattacks.

With modern web apps, automating any software integration becomes much easier. This saves you from juggling manual integrations and provides a more streamlined and optimised approach.

Serious Bottom-Line

Avoid costs of maintaining Legacy Software

Maintaining Legacy systems is expensive. Modern web apps architecture is designed to be simpler, quicker, and cheaper to maintain. Opting to take on the risks of legacy software means that time is working against you.

Software development trends move way too fast and old code falls behind. This leads to other challenges like incompatibility, integration, and development issues — exposing your system to security risks and vulnerabilities.

No need to build 2 separate mobile applications

A progressive web application (PWA) is a modern cross-platform solution that functions effectively on both iOS and Android. It’s fast-loading, engaging, has offline capabilities, and is easy-to-install. Building a single PWA means you don’t have to hire two different sets of engineers to build two separate apps that require different sets of code and technologies, and so on. You save big on time and costs.

Easily find and hire world-class talent

Traditionally, code written for legacy software is heavier, inefficient, and more complicated. Maintaining and integrating these systems requires a substantial HR investment in time, effort, and engineering talent.

Depending on when the system was developed, you may discover that finding and hiring engineers capable of understanding the code and being willing and able to take on the job becomes more expensive, if not nearly impossible.

A study by Avanade found that modernizing your legacy software could lead to 14% increase in revenue.

Get To Know Your Way Around The Challenges Involved In

1.

Missing Native Device Features

With Native apps, developers can use the full functionality of a device. Thus far, this has not been completely possible with progressive web apps. There are still a several native device features missing, but as with all technology, things are evolving rapidly.

2.

Microservices Can Bring Complexity

This is the primary negative of the microservices approach — the complexity of any distributed system. But these drawbacks can be addressed easily with the right automation tools and the right software engineers on the job.

3.

Availability & Scalability

More than just one application, it’s the creation of several linked services, each of which has to function flawlessly at all times. If one application becomes overloaded it is possible to create and adjust to accommodate higher numbers of requests. But there are still challenges involved in scaling up applications, which is where event-driven architecture (EDA) is opening new horizons.

We believe web apps should be able to do anything native apps can.

How To Move Forward With

Some issues to consider

Now that services are independent, it can become tricky to maintain requests moving between different modules. This can give rise to complications.

The more services, the more resources required — making it a challenge to manage transactions and multiple databases.

Global testing is also a challenge. You must confirm each dependent service before testing can happen. In addition, each service has its own logs, which makes debugging issues much harder.

So how do you move forward with this approach?

Web app development trends are constantly evolving, and the bottom line is that developers will need to know and understand the best route to take for each specific case. For example, for a smaller company, an initial monolithic approach might be easier and possibly cheaper. And it can always be migrated to microservices at the right time if need be.

For really big companies, microservices would probably be a better approach at the outset, when uptime and scalability are necessary.

How Event-Driven Architecture Can Combat Availability & Scalability Issues

“An event-driven architecture uses events to trigger and communicate between decoupled services and is common in modern applications built with microservices.” – Amazon AWS

Event-Driven Architecture (EDA) focuses on events and how they flow through a system. This shift in focus has made it possible to change the way applications are designed. And by using message brokers (an application that acts as the go-between for the application that created the event and the event consumer), applications are decoupled, addressing any availability concerns. In a case where an application is temporarily unavailable, it will continue consuming and processing events that were triggered while it was down.

Also, services built in this way are created to be used in multi-instance situations. These services are stateless, meaning the state is stored in the event log making accurate scaling of any particular service, possible. There are always exceptions, of course. But usually simple solutions are easy to come by.

As the need for digital transformation increases, so more demanding requirements arise and businesses need to keep up to stay relevant. More complex requirements mean more need for newer methods, and EDA is one of these solutions.
