Application modernization pathways on AWS

AWS cloud application development is a robust method of designing, constructing, and maintaining software in the cloud. This approach improves the dexterity of development teams, as well as the reliability and security of applications, allowing you to build and launch innovative products quickly. Based on our over a decade of experience creating applications, we have identified three paths that clients can follow to transform their ideas of modernizing their solutions and creating value for their businesses.

1. Creating new applications on AWS with Kubernetes.

Businesses that are either currently operating Kubernetes on-premises or contemplating developing new applications on Kubernetes can utilize AWS to execute these workloads to enhance their reliability, security, and scalability. Adopting this method presents control over the server level, common operational tooling, and access to the extensive portfolio of AWS application development services in an integrated manner.

2. Developing applications on managed containers and serverless architecture.

With a view to enhancing agility and facilitating development while incorporating automation and minimizing server management, we suggest building new solutions or their features with managed containers, serverless technologies, and purpose-built databases.

3. Adopting a modern DevOps model.

With a focus on rapidly developed and deployed stringently secure and governed modern solutions with a high volume and a large number of users, businesses choose to employ AWS application development services and other DevOps tools.
We will delve into each of the mentioned pathways to demonstrate how they can improve agility, reduce expenses, and create modern solutions that drive business value delivery. It is possible to modernize applications from any point in their lifecycle with the outcome in the shape of secure, dependable, flexible, and readily accessible solutions.

Build new applications on AWS with Kubernetes

Whether motivated by the competition on the market, or enhanced value delivery, an increasing number of customers prefer revamping their organizations by developing new applications to leverage the cloud’s full potential. App modernization can be just as diverse as the multitude of applications and the states they are in. However, if something can be certain when it comes to modernization, it is the more frequent choice of containers: they offer a lightweight and flexible approach to deploying new applications. Containers are particularly useful for complex application architectures that count on fast deployment, flexibility, and continuous innovation possibilities regardless of the environment of the app.

So as to the switch to containerized apps, the resource allocation decision is among the first ones in question. The choice of the best-suiting container orchestration platform is of the greatest importance. While the market offers different opportunities for managing complicated deployments and automating the infrastructure, Kubernetes is a well-justified choice for those after open-source software. Being widely recognized as an extensive containerized app’s infrastructure, it is a highly flexible and scalable system with consistent open-source APIs for the seamless interoperation of multiple services and resources within an application.

Kubernetes allows running and managing containerized apps across different environments, including on-premises, in the cloud or in hybrid clouds. In order to increase the security and consistency of the Kubernetes-based workloads, many businesses take on Amazon Elastic Kubernetes Service (EKS). For various organizations, at any point of their modernization journey or experience with Kubernetes – Amazon EKS can be a favorable choice as it strengthens the app’s reliability and security with access to AWS services, operational tools and best-proven strategies.

To fully enjoy the benefits of Amazon EKS in both on-premises and hybrid environments, Amazon developed EKS Anywhere. As a deployment option, it enables keeping latency-sensitive or regulated applications in a private cloud on-premises, though it also provides a consistent toolset across multiple environments. EKS Anywhere helps take full advantage of EKS to create and deploy scalable and secure containerized apps in different environments.

Kubernetes is an extensive orchestration technology for deploying and running containers. For this reason, constructing a custom EKS cluster becomes a cumbersome and laborious process taking into account all the available open-source tools and AWS services which require advanced knowledge of both AWS and Kubernetes to be integrated and applied appropriately. In order to settle this need, Amazon created EKS Blueprints, a set of pre-built templates with pre-configured settings to simplify the integration of Kubernetes and Amazon EKS tools with a view to prompt app deployment without specialized expertise.

Why use Kubernetes for modern application development

As an open-source technology, Kubernetes enables running and managing containerized apps on any platform without modifying your operational tools. With a dedicated community supporting it, Kubernetes is consistently enhanced and updated. Moreover, numerous open-source projects and vendors offer Kubernetes-compatible software, enabling you to enhance and expand your infrastructure.

An example of such software which allows deploying Kubernetes clusters to bring about high security, scalability and availability to the infrastructure is Amazon Elastic Compute Cloud (E2C). With this method, organizations, which possess the necessary expertise in Kubernetes deployments, retain their control over not only compute instances, but also deployment, maintenance, and scaling procedures. Another undeniable merit to the use of E2C is the worldwide accessibility along with the dependability and resilience that AWS Regions and Availability Zones have to offer.

On the other hand, AWS Fargate provides a serverless environment for businesses that wish to bypass the burden of having to manage a compute infrastructure. Instead, this service allows:

  • Avoiding the operational overhead of scaling, fixing, securing, and administering servers.
  • Boosting security with workload segregation by default, with dedicated runtime environments for Amazon EKS pods.
  • Benefiting from the pay-as-you-go pricing and purchasing only the resources you actually use while running containerized apps.

Build on managed containers and serverless services

As stated above, the adoption of container technology is a common initial step for many organizations to modernize their applications. This shift enables them to avoid spending resources on operational tasks and dedicate time and effort to developing new features and applications instead. More and more companies are opting for AWS-managed container services like Amazon EKS or Amazon ECS with AWS Fargate, with a view to introducing ever more scalable, reliable, secure, and accessible solutions. What leveraging managed container services provides is the reduction in operational burden and freed-up resources to concentrate on team upskilling, and accelerated development of modern and more innovative applications using serverless computing.

How AWS defines serverless

According to AWS, serverless means developing and running applications and services without the need for operating servers. In a serverless architecture, infrastructure is automatically managed by the cloud provider which allows developers to devote their time and effort to writing code and delivering business value, without splitting their focus to server management issues such as capacity provisioning, software patching, or infrastructure scaling. The four fundamental principles of a serverless approach involve:

  • No server management
    Server provisioning, maintaining and managing are not included in the software design.
  • Flexible scaling
    Individual servers do not govern capacity allocation; scaling occurs automatically, e.g. on the basis of change in throughput, memory or other units of consumption.
  • Pay-for-value
    What you pay for includes such value-delivery enhancing features as consistent throughput or execution duration, rather than server units.
  • Automated high availability
    Developers can focus on innovation since the availability and fault tolerance have already been architected in the serverless apps.

Innovation with serverless

App modernization relies on using tools, methods, and approaches for developing agile solutions. The modern serverless infrastructure allows developers to enjoy responsiveness and accelerated innovation in crafting apps that comply with international security standards and automatically scale to millions of concurrent users globally.

Numerous app owners prefer the serverless-first approach to solution development which prioritizes the implementation of serverless services with the aim of increasing agility within the app stack. This strategy proved to render the benefits of dynamic scaling, cloud-native high accessibility, and automatic server administration combined with a pay-as-you-go pricing model. The main merit of serverless-first, as specified by developer teams, is time and effort released from the shifted focus to faster innovation and consequently time-to-market.
AWS infrastructure enables the development of front-end web and mobile tools and services, which can be built with ease. Applications built on AWS are highly secure, accessible, and scalable, providing a solid foundation for brands to deliver their services to a global audience.

Monoliths to microservices: architectural shift for modern applications

Admittedly, legacy monolithic architecture is easy in administering in certain circumstances, such as limited infrastructure scale. As the application expands, though, numerous challenges emerge, involving ownership redistribution of the solution within the teams and, more acutely, scaling. Monolithically predisposed to hard dependencies, app architecture resists scaling even in cases of strong accountability and assigned responsibility among the team members.

To be more specific, when working on a monolithic architecture, multiple developers have to navigate a shared release pipeline, which leads to challenges at various stages of the process. During development, engineers have to orchestrate change implementations to avoid breaking existing code, while any updates to a shared library require getting everyone on board at the same time. Additionally, attempting to quickly implement important fixes still necessitates merging changes in progress. Post-development, monoliths cause further obstacles when pushing changes through the delivery pipeline. Even minor amendments to code require coordination among engineers, merging code, addressing release conflicts, rebuilding the entire application, running test suites, and redeploying.

Microservices are an obvious reliable way out for an app’s agility and responsiveness. Complex, and cumbersome in maintenance and upgrading, monoliths are broken down into separate, more manageable components, the microservices. The latter then can be scaled, deployed, owned and administered independently by separate teams, resulting in the aforementioned increased agility and scalability.

An application built with a microservice architecture consists of self-sufficient units, whereby each component is responsible for running a single process as a service. Microservices are created to perform specific functions and can be managed by a single development team. Hence, each microservice can be scaled, updated, and deployed independently to meet the demand for specific functions. Communication between independent units takes place through lightweight APIs, events, or streams, all of which are well-defined interfaces. Event-driven architecture, which swiftly responds to changes in data, is a cost-efficient means to boost application scalability, agility and resiliency.

Serverless-first for modern application development

What will take the burden of operational management off the list of your major tasks and allow you to focus on the core value-generating business activities is once again the serverless-first approach. Such processes as app monitoring, provisioning, cost allocation and management, deployment, security and compliance, etc. have already been taken care of if you choose microservices architecture. Prioritizing serverless technologies means making the most of AWS’s operational advantages in favor of constant innovation.

A serverless operational strategy enables developers to create and operate applications and services without having to worry about server management, supplemented by a cost-effective pay-as-you-go pricing model. The automation of the serverless-first approach also offers engineers numerous opportunities to allocate resources to the more prominent customer-facing aspects of the application instead of administering infrastructure. Lastly, this strategy will benefit the innovation and modernization processes with cloud-native agility and scalability.

Leveraging AWS Lambda and managed container services on AWS

Cloud computing evolution dictates the current mostly preferred computing options; for now, instances are not the only one available. In order to determine the best computing option for your solution, consider if self-managing infrastructure could improve your business, if you have the necessary expertise to apply the computing option in question, and if the additional effort invested in the chosen option is likely to bring value.

Many customers now choose to use container services such as Amazon ECS and Amazon EKS, or serverless compute services like AWS Lambda to avoid server management. Realistically speaking, the most common and optimal way is using a combination of services, e.g. the report has it that AWS customers find value in using both AWS containers and AWS Lambda, with around 80% of container customers also using Lambda. Not only this particular combination, but many other mixed uses of the like provide benefits such as managed services with strong integration to AWS infrastructure, support for various use cases, simplified complexity, and access to a large network of partners.

Transform to a modern DevOps model


Swift innovation earns many organizations a competitive edge. It has been proven time and again that investments in agility and speed-aimed practices and approaches promote experimentation and accelerate the release of new ideas associated with enhanced value delivery. For this simple reason, having administering and management issues sorted out, Amazon leverages modern applications to innovate within agile and scalable environments.

As per Amazon, modern application development lies in empowering individuals to achieve superior customer outcomes. The cornerstone idea behind it posits “products, not projects”. Essentially, this holistic approach entails that the teams’ responsibility includes not only product creation and deployment but also management and maintenance.

To be added, AWS’s decade-long experience in developing and running scalable, reliable and agile solutions also suggests the importance of autonomy within teams. The ownership issue has found its solution in assigning accountability for each component within an app’s lifecycle, inclusive of receiving customer input, charting the course, and building and running the solution, to the team so as to keep it motivated to produce value and results for end-users. In this way, Amazon has safe-proofed teams’ motivation and creativity with autonomy and risk-taking.

Encouraging ownership culture in modern application development is not an easy task, as it requires significant changes in mindset, team structure, and responsibility allocation.
