enterprise cloud computing architecture

Cloud Foundry, Mesos, Nomad, Kubernetes, Istio, Linkerd, and OpenPaaS are some examples of current industry-leading container orchestration platforms. What this means is that “control” over the design parameters of enterprise computing is starting to be highly distributed among cloud infrastructure providers, service operators and those that build and run applications on those services. Cloud service architecture defines the overall cloud computing services and solutions that are implemented in and across the boundaries of an enterprise business network. Containers and orchestration platforms help to have a scalable system by providing the required abstractions, automation, and operational tools. Furthermore… and even more importantly, Enterprise Architecture also facilitates the assimilation of extreme change, another even more daunting characteristic of the Information Age. In the end, the idea of “blueprinting” an ideal solution for an enterprise’s … These requests can be internal as well as external API calls. 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. © 2011 John A. Zachman, Zachman International, Inc. 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. This provides maximum security as well as guarantees resource allocation for API execution. At some point, my opinion is, someone better start working on this because the opportunities for changes are going to get more complex and more invasive and come at an ever-accelerating pace… and not only technology innovations but environmental shocks, regulatory proclamations and global competition. Sebastopol, CA: O'Reilly Media, Inc. (2009). Figure 1—Cloud-native reference architecture by the CNCF. 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. Join a community of over 250,000 senior developers. However, in general, an ESB is a monolithic system and doesn’t fit well with MSA. 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. 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. John provided additional concepts and practices around implementation strategies, a critical next step in exploiting the framework ontology - this was great!!! Cloud-native applications are all about dynamism, and microservice architecture (MSA) is critical to accomplish this goal. Combining cloud-native technologies with an API-led integration platform helps to increase productivity by having agility, flexibility, and scalability through automation and services. Docker is the most popular container image format. He designed the Framework. In fact, if you have your Enterprise Architecture stored in a repository, I think I would SIMULATE those changes before I actually made any of them to make sure I did not introduce any discontinuities or dis-functionality that would disrupt the Enterprise business. This pattern also increases one network hop in inter-microservice communication similar to a centralized API gateway. Please take a moment to review and update. CPU usage, memory usage, and in-flight-request counts (such as load balancer routing queue) are a few well-known load spike monitoring factors that help to compute scale in and out decisions. Managing these APIs is a necessity in today’s digital economy. 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. Are we doing the right things? 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. The biggest challenge facing the Information Age Enterprise may well be change, not only because of its increasing frequency, but because of the unpredictability of its sources including technological change, environmental change, economic change, regulatory change, market change, political change, cultural change… etc. ON THE OTHER HAND, if you DON’T have Enterprise Architecture made explicit and maintained or if it has NOT been designed to accommodate extreme complexity and extreme change, then I would start working fast and hard to create your Enterprise Architecture and engineer it to accommodate extreme complexity and extreme rates of change because Cloud Computing is not likely to be the last technology innovation you are going to have to address. An excellent seminar. An enterprise in any sector can integrate, expose, and monetize its business capabilities by digitizing entire value chains. An excellent course. Load balancing and failover features will be necessary and naturally fit into this kind of scenario. Dynamic API discovery and routing enables discovery and routing to application developers. Is your profile up-to-date? 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. MSA produces frequent releases and these need to be seamlessly rolled out into production. A single private jet API gateway can be attached to a cluster of microservices of the same type. Cloud Application Architectures: Building Applications and Infrastructure in the Cloud. In fact, I don’t think you can answer the question without Enterprise Architecture. A virtual conference for senior software engineers and architects on the trends, best practices and solutions leveraged by the world's most innovative software shops. When scaling out, ingress traffic should be routed to each container with a suitable load balancing mechanism. While microservices expose their capabilities as simple APIs, ideally, consumers should access these as integrated, composite APIs to align with business requirements. But there's so much more behind being registered. Finally, it all comes together’. A combination of API-led integration platform and cloud-native technologies helps to provide secured, managed, observed, and monetized APIs that are critical for a digital enterprise. Orchestration platforms perform a health check probe for each container and can auto-heal if something is wrong. Data management is the key element of cloud applications, and influences most of the quality attributes. This article describes a vendor/technology-neutral reference architecture for a cloud native digital enterprise that can be mapped into different cloud … Microservices aren’t designed from an end-users’ point of view, where users want access to the system with their business needs. Autoscaling is often utilized within web/app tiers within the baseline architectures mentioned. You will be sent an email to validate the new email address. Enterprise cloud is a computing model where businesses can access virtualized IT resources from a public or private cloud services provider on a pay-per-use basis. The term is generally used to describe data centers available to many users over the Internet. Receiving this training from the masters will most certainly keep measurable benefits going forward. Through his publications and training - his efforts to raise the bar for enterprise architecture make him the world renown professional he is today. It also refers to explaining the characteristics of these applications specifically made to address scalability. 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. If you cannot assimilate the forthcoming changes, you are destined to go into “Future Shock"… See Alvin Toffler, “Future Shock” Bantam Books 1970. A primary benefit related to EA and cloud includes seeing how and where newer, highly disparate cloud systems might fit with legacy versions. API-led integration provides a platform to enable enhanced digital experiences for consumers. 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. Integration Developer News is a leading source of information on business-critical integration technologies, including application infrastructure, ESB, SOA, SOA Governance, Cloud Computing, Business Process Management [BPM]. 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. Enterprise Architecture, as a discipline focused on connecting an enterprise’s current reality to one desired in the future, can contribute to enterprises when it comes to managing cloud-based systems. These reports can be utilized to monetize business capabilities by combining them with the defined business plans. However, even if these gateways merge into a single gateway concept, depending on the use case and the requirement, in some cases, it is good to use multiple gateways to have a clean and scalable architecture. 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. Privacy Notice, Terms And Conditions, Cookie Policy. Basic components of cloud computing. Agility, flexibility, and scalability are key to becoming a successful digital enterprise. Cloud Foundry, Mesos, Nomad, and Kubernetes are popular container orchestrators used in the cloud-native space. I can recommend this seminar with enthusiasm. Passionate. Even in the current economic down-turn, savvy companies are turning to EA and The Zachman Framework for help. This has been an eye opening experience. API gateways are the interception point to policy enforcement, capture stats, metrics, and analyze analysis to find out how APIs are behaving. 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. 3. The Zachman framework made me understand the value of problem solving. 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 By becoming a digital enterprise, a company can integrate and expose its business capabilities as APIs by digitizing an entire value chain. This week has been money very well spent. In addition to all application dependencies, environment-specific properties such as configurations, certificates, and credentials should be associated with the container runtime. He IS the father of 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. Platform-as-a-service (PaaS) provides a full stack of user interfaces, data, and services to develop cloud-native solutions. Note: If updating/changing your email, a validation request will be sent, Sign Up for QCon Plus Spring 2021 Updates. Knative, AWS Lambda, Azure Functions, Google Functions, and Oracle Functions are a few examples of functions as a service platform (FaaS). If you want to interact with others who think and talk like you do, and learn from the very best, then the Zachman International courses are for you! Even though we perform thorough testing, sometimes we need to roll back to a stable state due to a late-found error. To do this, each application should have a proper load balancer bound to a service name. In this podcast, Michelle Noorali, senior software engineer at Microsoft, sat down with InfoQ podcast co-host Daniel Bryant. IDN’s audience includes business and IT professionals, vendors, and industry analysts looking for product … Get the most out of the InfoQ experience.

Don’t think about it too long... get certified and join the growing community of Zachman Certified professionals. An API-led integration platform is essential for digital enterprises whether they start with a greenfield or brownfield implementation. API shaping optimizes bandwidth usage and enhances the user experience. He oversaw the overall engineering process, giving special attention to scalability and service delivery of thinkCube solutions. Facilitating the spread of knowledge and innovation in professional software development. Data Management. It aims to build sustainable ecosystems and foster communities to support the growth and health of cloud-native, open-source software. 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. Container orchestration and management layer helps to manage a large number of containerized application deployments across multiple container host machines. Articles API mediation and transformation integrates legacy systems by using mediation and message transformation. Cloud computing continues to evolve from a market disruptor to the expected approach for IT. Lots of energy and enthusiasm. Continue with passion – it’s really good. Figure 4—Configs, credential, and certificate association with the container. It was the honor to have met and learned from the legendary John A. Zachman himself, the Father of Enterprise Architecture. The Zachman Framework training enabled me to fully understand the power of this framework (the ontology). View an example. Figure 2—A reference cloud-native architecture for a digital enterprise. 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 … Cloud native has its own foundation: the Cloud Native Computing Foundation (CNCF). Would take other courses in future. Quite an enjoyable course. 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. 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. 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. This requires a governance model with policy enforcement. To mitigate such situations, we should have different deployment strategies. • DoD Cloud Computing Strategy [1] • DoD Cloud Computing Security Requirements Guide [2] • DoD Secure Cloud Computing Architecture (SCCA) [3] • Presidential Executive Order on Strengthening the Cybersecurity of Federal Networks and Critical Infrastructure (Executive Order (EO) … 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. Authentication and Security enforce standard authentication and security across all microservices. Here is a popular, new question that is posed to me: “What kind of impact is the rise in cloud computing having on enterprise architecture?”. Here is my response: 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. In this article, author Greg Methvin discusses his experience implementing a distributed messaging platform based on Apache Pulsar.
