Yet, most organizations are still struggling to make significant progress, owing to the shackles of their outdated tech stack.

But where do you start? How do you navigate the complex journey of transforming your monolithic applications into a sleek, future-proof arsenal? The answer lies in a comprehensive and structured approach that addresses not just the technological aspects but also the organizational and cultural changes required for a successful modernization. And recognizing the application modernization triggers is the first crucial step. These catalysts serve as the driving force for change, prompting organizations to embark on the transformative journey of modernization.

In this practical guide, we’ll provide you with a comprehensive checklist that covers the essential steps and considerations for a seamless application modernization process.

The Modernization Process Checklist:

1. Prioritize Applications – Not all legacy applications require an immediate overhaul. You can start by identifying the most critical systems that significantly influence your business operations. Then, prioritize these applications according to their strategic importance and the potential benefits they offer through modernization.
2. Align with Business Strategy – Modernization isn’t just an IT project; it’s a strategic business initiative to accelerate business transformation. Make sure that your modernization plan is in harmony with your organization’s overarching business goals and strategies. This will help you make well-informed decisions and prioritize initiatives that deliver the most value for your organization.
3. Involve Stakeholders – Application modernization is not a siloed endeavor. Engage key stakeholders, including business leaders, application owners, end-users, and IT staff, from the outset. Gather their input, address their concerns, and secure buy-in to foster a collaborative and inclusive process.
4. Plan a Phased Approach – Attempting a “big bang” modernization of all your applications simultaneously is a recipe for disaster. Instead, plan to modernize your applications in phases, prioritizing the most critical systems first. This incremental approach will help mitigate risks and allow you to learn and adapt as you go.
5. Focus on Minimal Viable Product (MVP) – For each phase, define the core functionality needed to meet your immediate business requirements. Build iteratively, starting with an MVP and then incrementally adding features and capabilities based on user feedback and evolving needs.
6. Implement DevOps Practices – Modernization is not just about technology; it’s also about adopting modern software development and delivery practices. Embrace DevOps principles by automating build, test, and deployment processes, fostering collaboration between development and operations teams, and implementing continuous integration and continuous delivery (CI/CD) pipelines.

The Technology Checklist:

1. Assess Cloud Readiness – Evaluate whether your applications can be refactored for a cloud platform with minimal rework. Cloud-native architectures offer scalability, flexibility, and cost-efficiency that are essential for modern applications.
2. Review Integration Needs – Catalog all integration points between your applications and other systems, both internal and external. Ensure that your modernized applications can seamlessly integrate with these systems to avoid disruptions and maintain business continuity. Remember, your applications don’t exist in a vacuum; they’re part of a larger ecosystem.
3. Consider Containerization – Containerization is a powerful technique that can significantly enhance the portability and scalability of your applications. Explore containerizing your monolithic applications using technologies like Docker to simplify deployment and management. In fact, according to a recent Forrester survey, 74% of organizations are already using or planning to use containers.
4. Explore Microservices – Break down your monolithic applications into smaller, independent microservices that can be developed, deployed, and scaled independently. This approach fosters greater agility, flexibility, and resilience, enabling you to respond quickly to changing business needs.
5. Enhance Security – Modernization presents an opportunity to implement robust security practices that are often lacking in legacy systems. Embrace modern security principles like zero trust, encryption, and automated security controls to protect your applications and data from evolving cyber threats.

The People and Organization Checklist:

1. Establish Governance – Define clear governance processes and policies for your modernized applications across their entire lifecycle. This includes areas such as change management, incident response, compliance, and risk management. Trust us; you don’t want to be caught off guard when things go awry.
2. Manage Change – Change is inevitable, but it doesn’t have to be disruptive. Proactively communicate upcoming changes to end-users, provide comprehensive training and support to employees, and address concerns to facilitate a smooth transition. Remember, people are the heart of any successful transformation.
3. Upskill Teams – Invest in training and development for your developers, operations teams, and other IT staff. Equip them with the skills and knowledge required to work with modern technologies, processes, and practices. According to a recent McKinsey report, 87% of companies face skill gaps in their workforce, so don’t let your team fall behind.
4. Embrace a DevOps Culture – Foster a culture of cross-functional collaboration, shared responsibilities, and continuous improvement. Break down silos between development and operations teams, encouraging them to work together towards common goals. It’s important to understand that DevOps is more than just a collection of tools; it represents a fundamental shift in mindset.
5. Partner with Experts – Engage experienced modernization partners who can provide expert guidance, augment your in-house teams, and help you navigate the complexities of the transformation process. It would be advisable not to go at it alone; instead, leverage the expertise of those who have been there before, such as the expert team of professionals at Utthunga.
6. Enable Analytics, AI/ML, and Data-Driven Insights – As you modernize your applications, build in capabilities for collecting and analyzing data, enabling advanced analytics, and leveraging AI/ML. These capabilities will empower you to make data-driven decisions and unlock new insights that can drive innovation and growth.
7. Evaluate Low-Code Options – In some cases, leveraging low-code development platforms can accelerate the modernization process and enable faster delivery of applications. Evaluate whether low-code solutions are appropriate for certain use cases and can help streamline your modernization efforts.

Don’t wait to be left behind in the dust. Start your modernization journey today and unleash the full potential of your applications to drive innovation, enhance customer experiences, and propel your business toward long-term success.

Imagine your factory’s production line, once the pinnacle of efficiency, now struggling to keep pace with evolving market demands. As technology relentlessly marches forward, many organizations find their existing applications needing help to keep pace.

According to an eye-opening survey by Forrester, a shocking 73% of manufacturers have over half their applications still running on aging on-premise infrastructures and outdated mainframes. Once a source of stability, these legacy systems, with their antiquated technologies, rigid architectures, and cumbersome workflows, have become hazardous technical debts restricting agility, limiting functionality and scalability, and compromising security.

To compete in the era of intelligent manufacturing, data-driven operations, and disruptive innovation, industrial firms need to take a hard look at rationalizing and modernizing their application landscapes.

Application modernization is the process of migrating, optimizing, updating, and transforming applications to align with current technological standards, industry requirements, and evolving user expectations.

The first step in the modernization journey is a comprehensive evaluation of each application considering technical fit, operational costs, utilization, and business value. The analysis identifies which applications should be retired, retained, repurchased, rehosted, replaced, rearchitected, or rewritten.

The ultimate goal of application modernization is to create a streamlined, modern portfolio that aligns with the organization’s digital transformation needs now and in the future.

But how do you know when it’s time to say goodbye to the familiar and embrace the transformative power of modernization? This blog post serves as your guide, exploring the key triggers that signal your manufacturing applications might need a makeover:

Integrating newer technologies like AI, ML, IoT sensors, and advanced analytics with legacy systems has become exceptionally difficult, requiring extensive customized coding and integration costs. On average, your legacy systems take 2-3 times more effort to maintain and cost over five times more per transaction than modern cloud-based applications.

Legacy applications severely constrain business agility and time to market with inefficient release cycles and the inability to scale rapidly. Monolithic applications make even minor tweaks slow and painful, while homegrown tools built for niche use cases create fragmentation. As a result, technical debt accumulates, manual workarounds become commonplace, and siloed systems start to obstruct visibility.

Modern industrial operations require applications that provides real-time insights, processes vast amounts of data, and executes complex tasks efficiently and accurately. Legacy systems simply lack the scalability and elasticity to meet such spikes in demand, eventually forcing you to over-provision infrastructure.

Maintaining multiple legacy applications entails high operational and maintenance costs, redundant functionalities, and inefficient processes and demands for specialized skills and hardware. Consequently, technical debt accumulates, making it increasingly difficult to innovate at the pace required today. Let’s not forget the tremendous number of servers and systems required to support this portfolio.

With cybersecurity threats constantly evolving, legacy platforms pose enormous security risks, as over 70% of breaches are tied to vulnerabilities in outdated systems. Built on antiquated architectures and lacking modern security features, they are particularly susceptible to shadow IT, cyber-attacks, and data breaches.

Evolving regulations often necessitate revamping aging applications that fail compliance requirements. Non-compliance with regulations like GDPR due to legacy apps can lead to heavy penalties for industrial companies. For instance, your legacy ERP systems likely lack the necessary security safeguards for sensitive financial data, like customer payment information, that are now mandated by regulatory standards. These systems simply weren’t designed for today’s security needs.

Unexpected events such as natural disasters, geopolitical tensions, and public health crises underscore the critical importance of business continuity plans. With their monolithic architectures and single points of failure, legacy applications can pose significant risks to continuity and resilience. Additionally, their inflexibility, coupled with poor failure provisions, may further amplify disruptions.

As you expand your industrial operations and enter new markets to serve increasingly diverse customer needs, scalability and flexibility become crucial. Legacy monoliths may limit your ability to scale on demand, adjust to dynamic needs, and enable organizational agility. Moreover, point solutions grown organically over generations could further constrain flexibility.

Industry leaders like Siemens emphasize data-driven manufacturing as the next frontier for exponential value creation. However, decades-old industrial legacy systems frequently lack the capabilities to fully leverage data and analytics, potentially impeding your organization’s capacity to derive actionable insights and make informed decisions.

Today’s consumers expect seamless omnichannel experiences with real-time responsiveness. Yet, legacy applications, burdened by fragmented data and inflexible interfaces, face considerable hurdles in meeting these expectations. The integration of modern customer experience features exacerbates this challenge even more.

Legacy systems and outdated applications can hinder your organization’s agility, affecting innovation, time-to-market, and responsiveness to market trends. As competitors adopt advanced technologies and processes, you may find your existing systems struggling to support new products, meet customer needs, or data-driven insights, potentially leaving you behind in the game.

Think about a production plant or a manufacturing unit, it is a visual cacophony of machines, robots, assembly lines, drives and many more parts, and yet completely (almost!) synchronized and working together. Bringing all of them together is the Industrial Internet of Things coupled with the open, Ethernet-based OPC UA communication standard that forms an critical part of the industrial automation landscape.

OPC UA does the job of integrating the IT/OT technologies with the diverse products, solutions and services across the entire OEMs, factory and process systems. Whether it is the security measures, networking, establishing standardized communication or needing a vendor and platform neutrality, OPC UA lays the foundation for a digitized industrial automation .

Connecting machine data to the enterprise

It is a fact that automation in the industrial world open doors for new business opportunities, enhanced solutions and services. But, the reality faced is how to effectively transfer the raw data generated from the shop floor equipment to the business applications like ERPs, CRMs; and draw insights to take actionable decisions for a competitive advantage.

Having a fully automated OEM unit or process system means having real-time and accurate information from these systems for analysis, machine alerts, maintenance notifications etc. based on your priorities. OPC UA provides two paths for this integration process:

1. Via customized development solutions and services through OPC UA stack APIs
2. Providing COTS solutions such as connectors, servers, clients etc. that connect your machines, field devices and other equipment etc. to the enterprise

OPC UA is the open source communication standard protocol designed specifically for industrial automation. It acts as a bridge that connects the IT with the OT, for information exchange between machines, devices or within devices. Implementation of this magnitude needs extensive software and hardware support through the OPC SDK that helps the stakeholders to overcome the various development and integration challenges associated with this process.

Consisting of APIs, OPC UA stack, protocols and sample implementations that support different platforms like Windows, Android, iOS, Linux, and programming languages like C, C# and Java; the SDK makes your devices, products and applications to be OPC enabled.

Meeting the Industry 4.0 requirements

Industry 4.0 mandates interoperability and standardized data connectivity for meeting its specific requirements including but not limited to

• Integration across all levels.
• Secure transfer and authentication at user and application levels.
• Conformity to industry standards.
• Scalability.
• Semantic mapping of various information models to represent the actual products and their production steps.
• Ability to plug-and-produce (instant discovery mechanisms that identifies OPC UA enabled devices and their functions when added to a network)

OPC UA serves as the common data connectivity and collaboration standard for local and remote device access in IoT, M2M, and Industry 4.0 settings. It supports OPC UA Server development, OPC UA Client Development and OPC UA Nano Server development for various communication mechanisms:

1. OPC UA client/server Model:

This one-to-one communication mechanism is used extensively in automation. The OPC server transfers the data to the OPC client based upon request in a secure, encrypted and reliable manner using the communication protocols such as EtherNet/IP, Modbus, etc.

2. OPC UA PubSub Model:

In the network, one-to-many or many-to-one communication mechanism is established. The data is available from the publisher, which can be accessed by multiple subscribers. Along with Time-Sensitive Networking (TSN) and cloud environment, OPC UA PubSub enables real-time communication at the control level (sensor, actuator or embedded devices) and meets the demands of time-critical applications.

3. OPC UA over TSN:

While OPC UA provides a standardized mechanism for data communication in a secure way; TSN is the infrastructure of vast array of sensors, actuators and other automation devices that extends the OPC UA information model down to the field level. TSN provides interoperability to the data link (layer 2) of the communication network. Thus, allowing guaranteed, optimized and scalable bandwidths for real-time capability and low latency in the network.
