The question this begs however is, how long will that last??? These reference implementations will be covered in separate papers. Enterprise Cloud Computing provides organizations with the ability to deliver computing services in a controlled and secure manner, since a cloud for the enterprise makes use of a network firewall. I doubt that you would want to change the manual, material handling aspects of your Enterprise based on Cloud Computing and you may not want to change your strategic or core systems; however, if you wanted to change any automated systems, and if you have Enterprise Architecture designed for accommodating complexity and change, then you should be able to: …all with minimum time, disruption and cost. An API gateway cluster can be scaled horizontally and the load is distributed among all the API gateway containers. Combining cloud-native technologies with an API-led integration platform helps to increase productivity by having agility, flexibility, and scalability through automation and services. Receiving this training from the masters will most certainly keep measurable benefits going forward. The instructors thoroughly covered concepts, demonstrated their application effectively and convincingly explained the consequences of poor architectural practice. The container network interface (CNI) enables APIs to plug in different container network runtime implementations and the container storage interface (CSI) provides a common standard to connect container orchestration platforms to plug into persistent storage. Practically, in the short term, I would try out Cloud computing and try to understand its utility and it risks… but at the same time, I would start making the long-term investment in Enterprise Architecture. Until I took the Zachman EA 4 day class, I didn't realize that all I had been doing was drawing incomplete views, since I didn't truly understand the relationships and the real impact to an organization of making a change to an architecture element. • Reese, G. (2009). To mitigate such situations, we should have different deployment strategies. A proper enterprise architecture practice can help bring clarity to the nebulous world of the cloud and help answer the critical questions to determine which areas make sense to pursue. His work has helped to drive strategy execution and subsequent business outcomes through his ontology, strategy mapping, matrixes and models. Enterprise cloud computing is the special case of utilizing cloud computing for competitive advantage through breakout opportunities both for cost savings and, more importantly, for business innovation in terms of unprecedented speed and agility with vastly improved collaboration among … Figure 2—A reference cloud-native architecture for a digital enterprise. I am so honored to have met him at training in Colorado and then again last October at a conference in Washington D.C. Digital enterprises can have in-house or cloud orchestration platforms to deploy these MSA-based applications, and, if enterprises use serverless functions, then it is recommended to use a FaaS platform provided by a well-known cloud provider. These APIs should be secured, managed, observed, and monetized. The term is generally used to describe data centers available to many users over the Internet. IBM constantly refines the Cloud Computing Reference Architecture (CCRA) based on the changing regulatory and compliance needs (based on the solid security and privacy frameworks). These reports can be utilized to monetize business capabilities by combining them with the defined business plans. Integrations are often supported by enterprise service bus (ESB) functionality such as routing, transformations, orchestration, aggregation, and resilient patterns. The container runtime interface (CRI) allows users to plug in different implementations of container runtimes. Authentication and Security enforce standard authentication and security across all microservices. Docker is the widely used container runtime. The U.S. Army Enterprise Cloud Computing Reference Architecture (AECCRA) is being developed incrementally to provide guidance for the Army’s transition to Cloud Computing. Individual microservices that are deployed as containers should be able to scale in and out depending on the load spikes. Combining cloud-native technologies with an API-led integration platform helps to increase productivity by having agility, flexibility, and scalability through automation and services. The same gateway cluster can be used to manage external APIs as well as internal APIs or can have a dedicated API gateway layer to manage external traffic. A single private jet API gateway can be attached to a cluster of microservices of the same type. This class has shown me the importance of getting down to the "brass tacks" of an EA, namely the Zachman primitives and their relationships. The only option you have is number 3 above, just build a new Cloud Computing implementation in which case. The book also covers the fundamentals of enterprise computing, including a technical introduction to enterprise architecture, so it will interest programmers aspiring to become software architects and serve as a reference for a graduate-level course in software architecture or software engineering. Cloud-native technologies are critical to accomplishing agility. It also refers to explaining the characteristics of these applications specifically made to address scalability. While microservices expose their capabilities as simple APIs, ideally, consumers should access these as integrated, composite APIs to align with business requirements. By becoming a digital enterprise, a company can integrate and expose its business capabilities as APIs by digitizing an entire value chain. Passionate. Once more I was able to pick-up new ideas and a couple of valuable best practices. This article describes a vendor/technology-neutral reference architecture for a cloud native digital enterprise that can be mapped into different cloud … API shaping optimizes bandwidth usage and enhances the user experience. By becoming a digital enterprise, companies in any sector can integrate and expose their business capabilities as APIs. Many wide ranging examples to demonstrate why. Running unnecessary containers wastes computing resources and having a short number of containers can cause service downtime. But there's so much more behind being registered. The developer experience is key to the adoption and success of your APIs, and having a feedback mechanism, such as customer ratings and forums, is key for a developer portal. Containers and orchestration platforms help to have a scalable system by providing the required abstractions, automation, and operational tools. Jaap Schekkerman discusses cloud service models, benefits and risks, and how cloud computing is going to influence the enterprise architecture. Data management is the key element of cloud applications, and influences most of the quality attributes. Orchestration platforms perform a health check probe for each container and can auto-heal if something is wrong. Are we doing them the right way? You can take refuge in the fact that the global playing field as it relates to Enterprise Architecture in 2011 is pretty flat… no one has substantial advantage. Cloud Application Architectures: Building Applications and Infrastructure in the Cloud. MSA helps to divide and conquer by deploying smaller services focusing on well-defined scopes. To expose system functionality as business APIs, these microservices need to integrate with different SaaS endpoints, legacy applications, and other microservices to perform the defined business functionality. Then, I would suggest Enterprise Architecture is fundamental to answering this more appropriate question. Very powerful. These smaller services need to integrate with different software as a service (SaaS) endpoints, legacy applications, and other microservices to deliver business functionalities. Abstract— Cloud computing provides services such as software, platform, storage, applications, network, etc, over the Internet based on a pay-as-you-use approach. These images should be stored in a registry where other developers, as well as runtime environments, can cloud-pull and create containers out of these images. I have been doing Enterprise architecture since 2003, mostly DoDAF and TOGAF. The infrastructure and orchestration layers represent the same functionality that we discussed in the cloud-native reference architecture. Please take a moment to review and update. Getting Zachman Certified is dollar-for-dollar the smartest investment an architect, any architect, can make. These APIs should be secured, managed, observed, and monetized. It explains the different kinds of desired transformations the architectural blocks of EA undergo in light of this strategically significant convergence. Microservices communicate with each other to complete a given business task. Subscribe to our Special Reports newsletter? The shared cluster of API gateways handles all API requests. Even though we perform thorough testing, sometimes we need to roll back to a stable state due to a late-found error. Platform-as-a-service (PaaS) provides a full stack of user interfaces, data, and services to develop cloud-native solutions. Cloud computing promises to fundamentally revolutionize enterprise IT systems across industries such as financial services, retail, telecom, government and education. Cloud computing is the on-demand availability of computer system resources, especially data storage (cloud storage) and computing power, without direct active management by the user. John Zachman gave me an excellent insight into the way EA practitioners think and operate, enabling me to express an organisation (as business architecture models) in their language. View an example. The sidecar pattern reduces the additional external network hops that are required in the centralized and private jet gateway patterns while having the local network call to communicate. Very educational, friendly and helpful lecturers. Most of you would agree that it is easier to get operational expenditure (OPEX) approval than capital expenditure (CAPEX), especially related to the following points: • No hardware or computing resources lingering on balance sheet • No depreciation • No need for lengthy justification • No monthly review of system utilization • No need to refactor computing resources after project completion • For the cost of a cappuccino a day, a user can access his own dedicated server Your continued support for John over the last few years is clearly appreciated and probably instrumental in his continuing to return to the UK. Zachman® and Zachman International® are registered trademarks of Zachman International, Inc. We have mobile networks, even for IoT, that don’t use 5G or MEC. min read. An excellent and inspiring seminar - we will return to work and start immediately. The runtime layer mainly consists of the container runtime. API load balance and failover enables scalability and high availability. Continue with passion – it’s really good. Allowed html: a,b,br,blockquote,i,li,pre,u,ul,p, A round-up of last week’s content on InfoQ sent out every Tuesday. Prior to co-founding thinkCube, Lakmal spent four years at ITABS, a company that specialized in Linux based server deployments that came with a custom easy-to-use server management interface. This is where API gateways are important. So… what do you do about Cloud Computing right now if you DON’T have Enterprise Architecture or if it is NOT designed to accommodate extreme complexity and extreme change? Clouds are considered Platforms-as-a-Service (PaaS), since a cloud provider supplies users with both the platform and the underlying IT infrastructure.Architecting a cloud platform requires more than just abstracting a computer’s capabilities from its hardware components, which is how providers create and offer cloud infrastructure to users. Knative, AWS Lambda, Azure Functions, Google Functions, and Oracle Functions are a few examples of functions as a service platform (FaaS). The container orchestration platform is scheduled and creates a container (runtime) in a worker node. Seven thousand years of known history of humankind establishes that the only known strategy for accommodating extreme complexity and extreme change is…. Cloud Computing and Enterprise Architecture by: John A. Zachman, Move the enterprise records off site to run on different. InfoQ.com and all content copyright © 2006-2020 C4Media Inc. InfoQ.com hosted at Contegix, the best ISP we've ever worked with. Microservices aren’t designed from an end-users’ point of view, where users want access to the system with their business needs. The enterprise and cloud computing master's program is intended to educate high-end IT professionals with an interest in enterprise and cloud computing. Comprehensive observability systems and business insight reports help to get an understanding of how these APIs are behaving. This requires a governance model with policy enforcement. API gateways are the interception point to policy enforcement, capture stats, metrics, and analyze analysis to find out how APIs are behaving. A Cloud-Native Architecture for a Digital Enterprise, I consent to InfoQ.com handling my data as explained in this, By subscribing to this email, we may send you content based on your previous topic interests. An API-led integration platform is essential for digital enterprises whether they start with a greenfield or brownfield implementation. An excellent seminar. Technology is evolving in a way that all types of gateways, such as API gateways, ingress gateways, service mesh gateways, and micro integrators, are merging into a single, all-in-one gateway. Cloud computing also typically delivers Web services, providing access to components that can be easily combined to rapidly create composite web applications to meet the ever changing needs of a business operation. At the most abstract level, governance seeks to ensure that what we are governing is doing the right things right: 1. Therefore, if you have Enterprise Architecture, and if you have made that Enterprise Architecture explicit, and if you have designed it correctly, you should be able to change the Enterprise and/or its formalisms (that is, its systems, manual or automated) with minimum time, minimum disruption and minimum cost. If you want to learn more about cloud-native digital enterprise architecture, read my paper about a vendor/technology-neutral reference architecture for a cloud-native digital enterprise. These requests can be internal as well as external API calls. A round-up of last week’s content on InfoQ sent out every Tuesday. The whole idea of Enterprise Architecture is to enable the Enterprise to address orders of magnitude increases in complexity and orders of magnitude increases in the rate of change. An excellent course. In this podcast Shane Hastie, lead editor for culture & methods, spoke to Emily Jaksch about the myths, misconceptions and realities of the millennial generation. Would take other courses in future. Ranks provides leadership for the Cloud Computing Program Office under the DoD CIO to ensure seamless support to our warfighters. In the end, the idea of “blueprinting” an ideal solution for an enterprise’s … Cloud-native applications are all about dynamism; microservice architecture is critical to accomplish this goal. This has been an eye opening experience. Combining cloud-native technologies with an API-led integration platform creates an effective architecture for a digital enterprise to increase productivity by having automation, production or operation, and services. Managing these APIs is a necessity in today’s digital economy. Move whatever you want out to a Cloud and see if it works… maybe, after you get it moved, you might want to evaluate the cost, disruption and time to move it and to operate it as well as any risks you have incurred by moving it outside of your jurisdictional control. I was anxious about my decision to take the virtual class but felt like I was in the classroom with you all. This pop-up will close itself in a few moments. Cloud computing continues to evolve from a market disruptor to the expected approach for IT. All CEOs and CIOs should attend. A sidecar is heavily used in service mesh architectural patterns. Apart from integration and API platforms, these architectures should be able to provide agility, flexibility, and scalability. Enterprise architecture, as a formal discipline, has arguably reached its ‘tipping point.’ Organizations are howling for change. Cloud Architecture An Enterprise Cloud is a hosted computing environment that delivers software, platform or infrastructure services to business users via a network. Three versions of the document are anticipated with each version being additive in scope to allow for the evolution and maturity of Cloud Computing technology. An enterprise in any sector can integrate, expose, and monetize its business capabilities by digitizing entire value chains. The most basic division of cloud computing architecture components is frontend and backend architecture with cloud infrastructure. What does a cloud architecture look like? The infrastructure layer represents the actual computing resources and the provisioning layer covers host management activities such as installing and setting up operating systems. Cloud-native applications are all about dynamism, and microservice architecture (MSA) is critical to accomplish this goal. Six Strategies for Application Deployment by Etienne Tremel, a Software Engineer at Container Solution, explains well-defined deployment practices in the cloud-native industry. Figure 5—Scaling, load balancing, and service name resolving. Offloading all service-to-service communication matters, such as discovery, reliable delivery, routing, failover, load balancing, etc., into a mesh sidecar will give freedom to developers to focus on business functionality. A shared API gateway adds an additional hop into inter-microservice communications. This week has been money very well spent. The fundamentals of this framework will help me to (re)engineer Enterprises and solve business problems in the shortest possible time. Every company is looking for an API-led integration platform to enable enhanced digital experiences for its consumers. Nobody can deliver the same quality of lecture as John. Get the most out of the InfoQ experience. 10 Gartner estimates that less than one-third of … The Zachman Framework training enabled me to fully understand the power of this framework (the ontology). An externally accessible self-service developer portal helps application developers or API users easily discover these APIs and use them with a well-defined business plan. Cloud-native application developers are mainly engaged with the functionality of the application definition layer, which defines application composition, application-specific configurations, deployment properties, image repositories, continuous integration/continuous delivery, etc. See our. In fact, if you have your Enterprise Architecture and if the Repository tool in which it is maintained enables you to do these kinds of simulations, then I would also simulate how these potential changes could affect your Business Strategies (Row 1), your Business Concepts (Row 2) and your System Logic (Row 3) including the strategic systems and core systems to see if they would be impacted or if you could capitalize on these technology changes to re-think the Strategies (Row 1), the Business Concepts (Row 2) and the System Logic (Row 3) for business advantage. Agility, flexibility, and scalability are key to becoming a successful digital enterprise. Krystian Rybarczyk looks into coroutines and sees how they facilitate asynchronous programming, discussing flows and how they make writing reactive code simpler. Container orchestration and management layer helps to manage a large number of containerized application deployments across multiple container host machines. You have three options: So, in short, the question, “What kind of impact does the rise in Cloud Computing have on Enterprise Architecture” is probably not the right way to ask the question. He designed the Framework. Health check and auto-healing is another important feature that comes with cloud-native orchestration platforms. Entities that […] The following are the key functionalities of an API gateway: Aligning with the MSA, API governance can be achieved via three main API gateway deployment patterns—Centralized/Shared, Private Jet, and Sidecar. In 2005, Lakmal co-founded the thinkCube, the pioneers in developing the next generation of Collaborative Cloud Computing products that are tailored towards Telecom operators. In this pattern, each individual microservice has a dedicated API gateway. Once the microservices are defined and implemented, they should be bundled with all their dependencies and shipped as container images. John shares his keen intuition for and understanding of the nature of enterprise architecture. Topics discussed included: the service mesh interface (SMI) spec, the open service mesh (OSM) project, and the future of application development on Kubernetes. Control and management planes should provide API management capabilities such as: Unlike monolith architecture, auditing and tracing are hard problems in decentralized architectures such as MSA. The panelists explore how a sound observability strategy can help mitigate operational costs and avoid common pitfalls in monitoring distributed systems. A Cloud-Native Architecture for a Digital Enterprise, Nov 17, 2020 Also, the main benefit of MSA is that it is easy to scale. Get a quick overview of content published on a variety of innovator and early adopter technologies, Learn what you don’t know that you don’t know, Stay up to date with the latest information from the topics you are interested in. This article describes a vendor/technology-neutral reference architecture for a cloud native digital enterprise and this can be mapped into different cloud-native platforms (Kubernetes and service mesh), cloud providers (Microsoft Azure, Amazon AWS, and Google GCP), and infrastructure services.
