Modernizing Your Digital Environment to Cope with Emerging Enterprise Needs

App modernization

Build Better Software Faster

With the rising demand for constant modernization, going obsolete is the biggest enemy of technology. How enterprises adapt to this trend may give them a competitive edge or a total loss. Modernizing your digital environment has become a necessity for business survival, not just a luxury.

The digital modernization journey does not end at one checkpoint. Depending on your business needs identified during the consulting phase, you might have to proceed to modernize or develop your applications, implementing DevOps or continuous improvement/continuous delivery, implementing fast data, and more.

How do we modernize app?


Transform the right app before transforming the app right Identifying which to automate (build up rather than bigbang approach). Well thought out project consulting can result to:

Faster Feature Delivery

Lower Development & Testing Cost

Fewer Bugs & Functional Changes

Proper planning and consulting plays an important role to the success on any major modernization transformation in an organization. When you want to make this transformation work for your organization, you need a partner who can help you realize the benefits and has the necessary expertise and experience to guide your organization on the myriad of tools/platforms and technical process that comes with this type of transformation.

Exist comes with a team of Technical Architects and Analysts that is backed with extensive demonstrable experience in providing technical consulting and implementation in modernizing an organization’s technical platform and process. Our team also has strong partnership relationship with domain leaders in the technology worlds whether that be cloud providers or development platform/framework vendors that allows us to also leverage their expertise on their respective domain to provide the best possible solution and value for our clients.

Bottom line of why we need to modernize our application architecture is that legacy applications (e.g. monolith) are difficult and slow to update, hard to scale both in performance and feature enhancements and does not seamlessly integrate with the modern Devops process.

Are you using monolith software?

There is no standard way of defining when an application is monolith or not. Below is guideline you can use to assess if your current application falls under the monolith characteristics:

  • All of the software components are assembled together and are tightly coupled
  • The application is too large and complex
  • It is hard to make changes fast and correctly
  • You must redeploy the entire application on each update
  • It is hard to scale since the modules have different resource requirements
  • A bug in any modules brings down the entire process affecting the availability of the entire application [Single Unit Deployment]
  • Difficult to adopt new and advance technologies [Language/Framework Lock]

When to migrate from monolith to microservices?

Not all monolith applications need to be migrated to a Microservice architecture (at least not yet). It is critical to start any modernization with an application assessment. It is important to take an inventory of what you have to start just about any transformation like this.

  • When the development team starts suffering from collaboration difficulties while maintaining the monolith [Cooperation Deadlocks]
  • Downtimes take too long which is detrimental in the era of online competition
  • Company is growing exponentially and the monolith software cannot meet modern demands
  • You want to reduce dependencies
  • You want to develop faster
  • You want to have smaller functions to test and debug errors on different levels easier wherein you can find mistakes faster and consume less time fixing it
  • You want to increase the amount of error-free deliverables

Monolith VS Microservices

MonolithicMicroservices / Containerization
All of its functionality is in a single processEach element of functionality is in a separate service
Lacks scalability
Can only scale in one dimension
[horizontal scaling only]
More scalable
Separate services make it easier to scale at a appropriate times without affecting other microservices
Application is too large and complex
to fully understand and make changes fast and correctly
Reduces complexity
The application is broken down into a set of manageable services which are much faster to develop, and much easier to understand and maintain.
Limited activity
Each change requires a full redeployment of the system
More agile
Changes can be done in one microservice rapidly
Poor fault tolerance
A single error can bring the whole software down since it is a single unit with many inter-dependencies
Resiliency and Fault tolerance and isolation
Failure of a single module will not affect larger applications
Continuous development/delivery is difficult
Updating a single component requires
Continuous deployment/delivery is possible
Smaller codebases and codes create

Data is the drivetrain of digital transformation. From understanding the customer better, improving business processes, identifying new opportunities for revenue, to balancing risk and reward. Having the right , flexible , scalable and modern data solution can enable your enterprise to tap into every available data asset, turning latent data into actionable knowledge and insight.

The basic model of transaction data, data warehouse or even big data may no longer be enough. Fast data is the next wave. Data that can provide real-time insights and also which can provide a lower footprint both in operational management and infrastructure dependencies will be a critical factor to compete on the next wave of innovation.

There is no silver bullet in implementing this new generation of data solutions but rather a combination of both tools and frameworks (e.g refer to App modernization), design, process and the right partner to help you realize the benefits of this model.

As the size and complexities of systems increase so does the organization’s dependencies to these systems to a point that it becomes an organization’s major platform to be successful and competitive in its industry. As such, it is critical to ensure the process of developing, deploying, fixing, monitoring, enhancing and overall management of the roadmap of these systems to be efficient, reliable and scalable as much as possible.

  1. Faster development cycle equating to faster time to market and faster innovation.
  2. Reduce deployment rollbacks failures, ensure efficient rollback process and time to recover.
  3. Increase development and deployment efficiencies with the help of automation process.
  4. Reduce IT Cost and allow to reallocate IT headcounts to other critical tasks

There are plenty of financial and operational reasons why an organization should consider moving to cloud deployment as there are also reasons why a company might need to migrate to an on-premise deployment or even a hybrid model. Whichever deployment platform is chosen, the modern architectural framework and devops process can be implemented whether it be on cloud, on-premise or even a hybrid model.

Cloud migration has been gaining plenty of interest since it provides organization a number of benefits on:

  1. Scalability – Cloud technologies allows scaling up and down depending on your requirements.
  2. Accessibility – Anywhere and anytime access.
  3. Costing – No upfront cost and only pay what you use which allows the costing to be also predictable.

Also, there’s no need to maintain servers and their racks, IT resources to manage those servers and server power consumption cost. Cloud providers also provides dashboard to allow you to keep in check of your running cost.

  1. Worry free IT – No need to maintain a dedicated IT group to manage your server platform as it will now be taken care of by the cloud provider.
  2. Security – Cloud data centers implements security measures beyond the affordability of most businesses, therefore your data is often safer in the cloud than on a server in the office.
  3. Quick deployment– accessibility and readily available tools allows for quick deployment of applications.
  4. Cloud managed services – Deployment in cloud allows the organization to take advantage of readily available cloud managed services from different vendors with majority on a pay per use billing model.

Cloud Migration Strategy

Cloud migration process can vary on different organizations based on factors such the type of migration (pure cloud, hybrid), components (e.g apps, database, devops, usage of cloud managed services), cloud provider (e.g. Azure, AWS, GCP, etc) among others. Whatever the variance, the common steps in cloud migration process would include the following :

  • Assessment of client’s cloud accessibility (bandwidth and connectivity)
  • Assessment of performance and security requirements;
  • Cloud provider assessment
  • Optimal Cost assessment (Pay per use and Reserved instance costing)
  • Change management assessment
  • Planning is critical as lack of planning would negate the value that cloud deployment offers.

Finding the right partner

Deployment and infrastructure migration can have a significant impact to an organization borth operationally and financially. When you want to make this type of migration work, you need a partner who can help you realize the benefits of this migration. Our team of technical resources has a good number of years successfully developing, migrating deploying cloud based systems for medium to large enterprises and for critical industries such as banking and finance and healthcare.
