Strategic Approaches to IT Infrastructure Modernization: Evaluating Custom and P...

Navigating the Path to Data Architecture Modernization

In today’s digital arena, organizations are increasingly seeking to offer cutting-edge services, a goal that necessitates IT infrastructure modernization for peak performance. A common challenge encountered is the Single Point of Bottleneck (SPOB) – a critical congestion zone that hampers the entire infrastructure. This bottleneck leads to inconsistent user experiences, characterized by slow response times and potential service downtimes. Triggered by the surge in digital services and mobile traffic in recent years, SPOBs pose a significant threat to efficient data handling, which is vital for the functionality of modern services and applications.

To navigate past the pitfalls of tightly coupled architectures and SPOBs, organizations typically adopt one of two strategies:

• Data Virtualization: This approach serves as a bridge, facilitating the integration of existing infrastructure with new applications. Data virtualization, acting as a form of middleware, effectively breaks down data silos. However, its performance is tethered to the underlying system it supports. As data volumes balloon, scalability and latency issues become increasingly pronounced, posing a challenge to maintaining efficient data virtualization.
• API Management: This method revolves around the creation, supervision, and control of APIs within a secure, scalable environment. It is essential in meeting the diverse needs of developers and their applications. API management tools enhance agility and security, streamline workflow tasks, and support advanced analytics. They also provide vital features like rate limiting, user access control, and token authorization. However, designing high-availability applications at scale demands sophisticated professional skills. The API Gateway, being the sole mediator between front-end interactions and APIs, also becomes a potential single point of failure. This can lead to performance degradation under certain scenarios.

In choosing the right path for IT infrastructure modernization, it’s crucial to weigh these considerations carefully. The decision not only impacts the current operational efficiency but also sets the stage for future growth and adaptability in the ever-evolving digital landscape.

Revolutionizing IT Infrastructure with an Operational Data Hub

Adopting an Operational Data Hub (ODH) – also referred to as Digital Integration Hub (DIH)  architecture –  represents a transformative approach in IT infrastructure modernization. This strategy effectively separates enterprise Systems of Record (SoRs) from their digital counterparts. By doing so, the ODH alleviates the typical bottlenecks found in conventional IT architectures—those that stymie innovation through slow, outdated, or costly access to SoRs.

At its core, the ODH employs an event-driven architecture, establishing a cohesive data layer. This setup not only facilitates ultra-low latency but also assures near-linear scalability. While primarily geared towards operational data, the ODH is versatile, handling analytics, notification services, and data integration with ease. Its deployment significantly enhances business agility and ensures a continuously updated view of rapidly evolving data.

The key benefit of an ODH is its ability to dramatically reduce the development cycles of new digital services. Moreover, it enables organizations to efficiently scale, accommodating millions of simultaneous users, regardless of the underlying IT infrastructure or cloud configurations.

For a comprehensive understanding of operational data hubs, the Operational Data Hub Handbook is available for download, offering detailed insights and guidance.

When designing an ODH, certain critical capabilities should be prioritized:

• Data Consolidation: Ability to amalgamate data from various sources.
• API-Based Access: Ensuring standardization and security through API-based access patterns.
• Low-Latency Architecture: Implementing a low-latency request-response system to optimize user experience.
• Data Integrity: Maintaining the most accurate and current data for reliability.
• Versatile Deployment: Supporting hybrid, on-premises, cloud, and multi-cloud environments.
• High Availability: Guaranteeing near-total business continuity across the architecture.
• Data Management: Addressing data quality, consistency, and scalable processing for pre and postprocessing.
• Multi-Modal Data Support: Catering to diverse business requirements with multi-modal data structures.
• Event-Driven Architecture: Embracing event-driven solutions to enhance IT modernization and provide timely notifications within the organization.
• Integration with Governance Tools: Linking with catalog systems (data, services, etc.), governance tools, and SIEM systems for streamlined management.
• Workflow Management: Offering advanced tools for workflow, pipeline management, and visualization.
• Cost Efficiency: Reducing infrastructure expenses by reducing calls to the backend sources, optimizing licensing, and reducing support levels.

The introduction of an ODH offers a blend of speed, scalability, and flexibility that is essential in today’s fast-paced digital landscape.

Deciding Between Building or Buying an Operational Data Hub

In this section, we delve into the pivotal ‘build vs. buy’ decision in IT infrastructure modernization. We aim to unravel this dilemma, prompting critical questions and offering insightful answers. The current business environment demands continual innovation in digital services. Consumers expect not only groundbreaking services but also demand immediate and accurate interactions. Failure to meet these expectations can lead to a loss of customer interest. Therefore, organizations must have a robust and efficient IT stack.

Before exploring the specifics of the stack, it’s essential to consider the often-overlooked costs of developing a custom solution:

• The real cost of open source: While seemingly cost-effective, open-source solutions can entail higher long-term expenses due to limited documentation, support, and other related factors.
• License costs reflect R&D investments: Companies invest heavily in product development, often involving hundreds of man-years. The licensing fees are not just for the product but for the extensive research and development behind it.
• Purpose-driven construction: If the primary goal is the assembly process itself, like building with LEGO® or assembling puzzles, then dedicating time to construction makes sense. However, when the objective is functionality – like traveling from point A to B – opting for a pre-integrated solution, such as a car, is more time-efficient than building one from scratch.
• Pre-integrated vs. from scratch: Pre-integrated solutions, akin to IKEA® furniture, offer a middle ground. They arrive disassembled to save on storage and shipping but require less effort than building from raw materials.

Considering these points, here are some key factors to evaluate before deciding to build an ODH:

• Effort: Assessing each component involves a thorough process – examining the company, attending technical sales meetings, demonstrations, proof of concepts, and procurement. This process might need to be repeated for each category.
• Cost: Licensing fees for different products can add up, especially when they come from various companies, often without the possibility of discounts.
• Integration Challenges: Assess the effort required to integrate each product into the existing ecosystem.
• Technology and Support: Determine whether the technology is nearing its end-of-life with limited support, or if it’s so new that support is scarce.

While it may initially seem more cost-effective to build an ODH with in-house resources, a deeper analysis might reveal that purchasing a pre-integrated solution could be both cheaper and more efficient in the long run.

Exploring Off-the-Shelf Solutions for Operational Data Hubs

GigaSpaces presents an off-the-shelf platform-based Operational Data Hub (ODH) capable of seamlessly connecting to various sources. This hub is designed to consolidate, process, transform, and deliver data with exceptional performance. It features a wide range of integrations, encompassing capabilities such as real-time ingestion through embedded Change Data Capture (CDC), batch ingestion via Extract, Transform, Load (ETL) processes, and other vital ecosystem components.

At the heart of this platform is the Data Access Layer (DAL), which fundamentally changes how digital business applications and services interact with SoRs. By deploying services directly onto the data fabric, the DAL eliminates the need for repeated SoR data accesses, enhancing efficiency and performance.

In this architecture, digital services access data through standardized APIs, predominantly RESTful interfaces. This shift centralizes data consumption to the micro and macro services within the data fabric itself. Such an architectural shift addresses and resolves the common anti-patterns that many organizations face, which typically lead to latency and throughput bottlenecks. This improvement is depicted in the following diagram:

When a business service requests data, it does so through a REST API. The system ensures data security by implementing authorization and authentication processes and assigning the necessary certificates from a trusted enterprise vault at the API Gateway level. The request is then securely transferred to the macro data access service within the DIH data fabric via a northbound entry point, equipped with the appropriate credentials and certificates. If the service requires a hosting layer, it operates as a streamlined microservice, delivering ultra-low-latency responses.

Evaluating IT Maturity in the Context of Business Excellence

IT maturity is an integral metric that reflects the alignment and effectiveness of IT capabilities in fostering exceptional business performance. Recognizing that each enterprise has its distinct operational dynamics, it becomes evident that IT capabilities and their utilization are uniquely tailored to each organization’s specific context. Whether an organization maintains a robust, internal IT department or engages external IT service providers, a critical imperative remains consistent: the prevention of an ‘IT Gap’, which could significantly impede the rapid deployment and adoption of new products and services.

The realization of optimal outcomes in IT, and subsequently in overall business performance, is contingent upon a multifaceted framework:

• Process Optimization: The refinement and efficacy of internal operational procedures.
• Adherence to Best Practices: Implementation of industry-standard methodologies and protocols.
• Strategic Organizational Structure: The deliberate configuration of team and departmental collaborations to maximize efficiency and innovation.
• Skillset Proficiency: The breadth and depth of technical and domain-specific expertise within the organization.
• Knowledge Management: The systematic sharing and application of collective organizational intelligence.
• Governance Policies: The establishment and enforcement of comprehensive IT governance frameworks.
• Technology Deployment: Strategic selection and utilization of technological solutions aligned with business objectives.
• Data Capitalization: Effective accumulation, analysis, and application of data to inform strategic decision-making.

From the vantage point of IT maturity, these factors collectively constitute the foundation for achieving IT excellence. This excellence is a precursor to advancing business maturity, spurring innovation, and amplifying productivity. Product managers and business strategists are increasingly focused on automating service delivery, developing intuitive, self-service customer interfaces, and diversifying engagement channels to include web, email, messaging, and mobile technologies.

In essence, a thorough appreciation and augmentation of IT maturity transcend mere technological considerations, encompassing a holistic strategy that integrates process management, human capital, and policy development. This comprehensive approach is pivotal for businesses to navigate and succeed in the rapidly evolving digital marketplace.
