WHAT IS MULTITENANCY?

@ITCAMPRO #ITCAMP18Community Conference for IT Professionals
The term "software multitenancy" refers to a software architecture in
which a single instance of software runs on a server and serves multiple
tenants.
A tenant is a group of users who share a common access with specific
privileges to the software instance.
With a multitenant architecture, a software application is designed to
provide every tenant a dedicated share of the instance - including its
data, configuration, user management, tenant individual functionality
and non-functional properties.

Talk presenting the concepts of Service Mesh, Serverless and Tracing as simply as possible. This was presented at the Paris Container Day 2018 on 26th June 2018, in front of 100 people. Below is the abstract of the talk: Some weeks ago, I was at the KubeCon + CloudNativeCon EU. 3 main topics that are not as well-known as they should be were mentioned a lot: - Service Mesh - Serverless/FaaS - Modern observability / Tracing For most people, these topics are really fuzzy since they are somewhat recent. It's easy to wonder what Service Mesh offers compared to traditional Load Balancing, what technology you should pick among Linkerd, Conduit, Envoy, Istio, when they all seem to do the same things. For Serverless and FaaS, one could wonder what they bring to the table when we already have orchestrators and containers that we can deploy in one command. And finally, it's easy to get lost among all the monitoring paradigms: metrics, logs, tracing... why everyone and every product is onboarding some tracing capabilities recently? We'll talk about all of this during these 20min. It may seem a lot, but we'll go straight to the point as "what's the need it's looking to address and why should I care"

AGILE: Building the Open Gateway for IoT

AGILE IoT

The phrase “cloud-native” has become overrated in today’s tech scene. Every familiar enterprise technology product is now rebranded as “cloud-native” and is offered as a containerized workload for today’s business needs. But are they really “cloud-native” ? To answer this question we have to deeply understand the cloud native qualities. Can our existing enterprise monoliths become cloud native or use cloud native tools ? is it worthwhile to break down the monolith as today’s advice goes ? This deck focuses on those hard questions in today’s enterprise landscape. This is a discussion with enterprise architects on the challenges they face in their cloud native journey.

The microservices architecture expands the attack surface with multiple microservices communicating with each other remotely. It’s a common principle in security that the strength of a given system is only as strong as the strength of its weakest link. Unlike in any other system design, the repercussions will be extremely highly if we do not get right the security in a microservices design. The key driving force behind microservices architecture is the speed to production (or the time to market). One should be able to introduce a change to a service, test it and instantly deploy it into production. A proper secure development lifecycle and test automation strategy needs to be there to make sure that we do not introduce security vulnerabilities at the code level. We need to have a proper plan for static code analysis and dynamic testing — and most importantly those tests should be part of the continuous delivery (CD) process. Any vulnerability should be identified early in the development lifecycle and should have shorter feedback cycles. There are multiple microservices deployment patterns — but the most commonly used one is service-per-host model. The host does not necessarily mean a physical machine — most probably it would be a container (Docker). The DevOps security needs to worry about container-level security. How do we isolate a container from other containers and what level of isolation we have between the container and the host operating system? How do we authenticate and access control users to microservices and how do we secure the communication channels between microservices? All fall under application level security. This talk addresses multiple perspectives in securing microservices: SDLC, DevOps, and application-level security.

“The whole is greater than the sum of its parts” - In this world of disaggregated, cloud native architectures, developers are increasingly adopting micro services to build Complex Systems. APIs play a huge role in creating a sustainable platform and a good API driven micro services design is key to building and scaling these complex systems. Whilst API Management and API Gateways have traditionally been used for north-south communication, Service Meshes and specialised gateways have emerged to handle complexity for East-West communication. The “parts” work, but is the “whole greater than the sum of its parts”? That’s the objective of this talk. We apply method to madness, and take a critical look at the role of APIs in cloud native, service mesh driven complex system design. We will look at how various API technologies including full lifecycle API Management, API Gateways and Micro-gateways, API Proxies and frameworks to build on-the-fly gateways play with Service Meshes like Istio and LinkerD, proxies like Envoy and ingress gateways. We will also look at practical examples of how full lifecycle API Management play an important role in Service Mesh based K8S Infrastructure.

It was 2015 when Microsoft first announced Azure App Services. Since then the platform has gone through a lot of changes and tons of new capabilities and features were added. Especially when looking at Logic Apps. After the change in the engine and designer the first SAP Connector was removed from the platform, but recently the new SAP Connector was released in public preview. Now that the new SAP Connector is finally available Glenn will demonstrate how easy it is to build enterprise level integration scenarios with the SAP Connector for Logic Apps.

The industry seems to be moving away from pure open source businesses. WSO2 is going the opposite direction, maintaining a strong commitment to open sourcing our products and open sourcing even more of our IP, building communities, making expertise available to our customers, and bringing transparency to our business culture and operations. This session explains why we believe our strategy of openness is fundamental to the success of WSO2 and our customers.

So you heard about containers, you played around with them, you're now cozy, but now you're in the situation where you need to ship the container(s) in production. Working with containers is pretty easy on your local machine but when it comes to hosting it somewhere on the internet, whole different problem arrises. On what infrastructure do I host them? I heard of Docker Swarm, Mesos, Kubernetes. Which do I pick? What should I know? This session will focus on the container solutions in Azure and what you need to know about the infrastructure that you need when you want to go into production with a containerized application.

SQL Server had, has and will certainly have a lot to offer, but the number one concern for a common developer when it comes to SQL Server is the management cost involved. This also happens to be the number one reason for why Azure SQL Database is so successful for hardcore developers who simply don’t want to become accidental DBAs and worry too much about the SQL production workload health. Throughout this fun session, I will demo (a lot!) and walk you through the techniques and technologies Microsoft brought to bring Azure SQL Database’s game up a few notches. These will literally make you, the developer, more productive and your application, more performant.

Each year the IT world offers a hype-word. The last decade has all been about mobile, cloud, Big Data and IoT. In the context of cloud apps however, monolithic applications have little to offer in terms of HA and DR and their deployment process is mostly an error-prone operation. Curious enough, even though container have been around for many years, the hype word nowadays is containers (along with microservices), and that’s probably because of Docker, who made containers really easy to use. Throughout this talk, I will cover the importance of containers and what Azure has to offer in terms of containers, namely Azure Container Services. And because deploying a single container isn’t part of the real world scenarios, I will also show you how you can manage (aka orchestrate) an application in the real world. Don’t be fooled by the title though! This session will not be exclusively about Docker, it will be about containers, about Docker images, about orchestrating containerized applications, about Azure Container Service, about deploying ASP.NET Core Applications to Docker Containers in Azure and about configuring release pipelines in Visual Studio Team Services and taking advantage of Docker containers.

Both CQRS and Event Sourcing are by no means “new stuff” anymore, yet a lot can be told about how to use Azure’s PaaS to implement such patterns and unleash their power. The ingredients are: DocumentDB as the event storage, Service Bus as the events’ dispatcher, Could Services/Service Fabric as the scalable, fault tolerant business logic container, SQL Azure as the read model and ASP .NET Core as the application framework used to implement views and back-end services. Eager to know the recipe? Don’t miss this talk then.

In this session, we will take a look at what we need to keep on our radar when we start a new project inside the Cloud. When not only us but also clients are new to the Cloud ecosystem, we need to be aware of small things that can make a difference or secure the success of the project. Things like security, environment isolation and access controls are just a tiny part of the things that we need be aware. There will be examples from real life projects and hands-on implementations inside Microsoft Azure. After joining this session, you will have an initial view on what things we shall be aware when we start a new project inside the Cloud.

Thanks to the recently released v4 of the Bot Framework SDK, creating your first bot is a breeze; still, implementing a production viable one is no easy task since several aspects must be taken into account such as user authentication, integration within existing apps, multi language support, technical considerations (e.g.: Azure Functions vs. MVC Core, Blob Storage vs. CosmosDB) and, last but not least, operational costs. Moreover, you might want to reuse your bot’s Azure hosted, Cognitive Services-backed code to address Amazon’s Alexa users to avoid the need to implement (and evolve) it twice. Eager to learn how to do that for real? Don’t miss this code-based talk then.

If there is a common practice in architecting software systems, it is to have them store the last known state of business entities in a relational database: though widely adopted and effectively supported by existing development tools, this practice trades the easiness of implementation with the cost of losing the history of such entities. Event Sourcing provides a pivotal solution to this problem, giving systems the capability of restoring the state they had at any given point in time. Furthermore, injecting mock-up events and having them replayed by the business logic allows for an easy implementation of simulations and “what if” scenarios. In this session, Andrea will demonstrate how to design time travelling systems by examining real-world, production-tested solutions.

Understanding skills is key to managing any organisation. Skills are not necessarily related to your job, your qualifications or your studies, they are related to what you can do and the responsibilities you have (or should have) within your organisation. Through a systematic and structured approach to understanding, analysing and classifying skills, the business can become more effective, staff has a better understanding of their roles and responsibilities, there is increased job satisfaction, and clear career and training progression plans can be defined.

Color. It has the power to evoke emotions and empower the effectiveness of a product, but it also has the ability to ruin otherwise meticulously crafted user experiences. It often rules from the shadows, disguised as a purely aesthetic element and a mean of beautification. Let’s see how to overtake control and strategically use color in digital product development. Product teams often fail to remember that color has an enormous impact on our response to visual stimulation during human-computer interaction. The most immediate and direct psychological impact on experiences is of course - color. With its complexity and various levels of subconscious effects, it triggers an emotional response. Color doesn’t live in a vacuum, and we need to start considering it in the context of use. There are many aspects that we need to take into account: target audience and their potential visual impairments, cultural background and individual difference, previous experiences and memories, the physical environment of use and compliance with the brand. In this talk, we will immerse into approaches and best practices that product teams should take for strategic use of color in their product design process. After a basic introduction to color theory and psychology (to make sure everyone is up to speed), we will elaborate in detail how even subtle differences in color schemes have a significant impact on interface perception and product success. We will show a series of interface examples we tested on various users and do some live testing on site as well.

Clean Architecture as a term is around for a while. However, the path to implement it is not always clear nor easy to follow. When projects fail for reasons that are primary technical, the reason is often uncontrolled complexity. The complexity goes out of hand when the code lacks structure, when it lacks Clean Architecture. In this session, I will show how to achieve consistency by implementing Clean Architecture through structure, rather than relying on discipline only. We will look at some basic building blocks of an application infrastructure which will enforce the way dependencies are created, how dependency injection is used or how separation of the data access concerns is enforced.

Well hold on there because there are some aspects you need to consider before you start rushing to production. How you will handle auto-scalling? What about updates / upgrades? Downtime of your app? Version 1 and Version 2? CI/CD? Etc. This session is about deploying your services on containers using the Azure Kubernetes managed offering.

Andy Cross, Director of Elastacloud, Microsoft Regional Director, Azure MVP and all round good guy, gives a session on how to successfully build or transform a business using AI technologies. Over the last years, Elastacloud have delivered analytics projects to a variety of customers. The greatest challenges around AI are both technical and organisational. The existing landscape of process and strategy doesn't solve these challenges in combination, and the gap between causes friction and the failure of AI projects. When modelling the outcome of actions that were informed by AI, possibly enacted by AI, the standard risk modelling approaches need to be transformed to include a factor that can change over time to represent the effectiveness of the AI solutions. Given that we should accept errors as part of the AI solution, and that errors are reinforcing of better future decisions, we need to project risk as a decreasing vector over time.

Marcus Vitruvius Pollio, commonly known as Vitruvius, was a Roman author, architect, civil engineer and military engineer during the 1st century BC. He is known for his multi-volume work entitled “De architectura” and his discussion of perfect proportion in architecture and the human body, which led, among others to the famous drawing by Leonardo da Vinci called the “Vitruvian Man”. Within the principles of “Vitruvian Quality”, we seek to find those perfect proportions and how to align all components of the business architecture in order to make them fit the human needs of the impacted stakeholders.

This session might look like a joke, and it partially is. On one hand it is a parody about how the most recent trends in industry can significantly increase the cost associated with launching an application (design, development, hosting & operations, etc). However, it is also a live demo of how you can incrementally evolve your application to take advantage of all the cool technologies out there without needing the actual a million dollars.

With the new model, Azure Resource Manger Microsoft are gaining the repeatability they always wanted to have for deployment to the Cloud and removing the dreary, repetitive, error prone manual deployment tasks which has always held us back! With ARM, you can create a Template for your environment and use that for deploying identical environments every time without fail! There is some news in the world of “infrastructure as code” that we need to consider while setting up our Cloud environments. The Win we get from being able to deploy our development environment or our temporary load test environment automatically and identically to our production environment cannot be understated. This is ARM from a project efficiency, development and DevOps perspective. This is what you need to know to make you much more efficient every day of development.

Heather Hedden, Senior Consultant at Enterprise Knowledge, presented “The Role of Taxonomy and Ontology in Semantic Layers” at a webinar hosted by Progress Semaphore on April 16, 2024. Taxonomies at their core enable effective tagging and retrieval of content, and combined with ontologies they extend to the management and understanding of related data. There are even greater benefits of taxonomies and ontologies to enhance your enterprise information architecture when applying them to a semantic layer. A survey by DBP-Institute found that enterprises using a semantic layer see their business outcomes improve by four times, while reducing their data and analytics costs. Extending taxonomies to a semantic layer can be a game-changing solution, allowing you to connect information silos, alleviate knowledge gaps, and derive new insights. Hedden, who specializes in taxonomy design and implementation, presented how the value of taxonomies shouldn’t reside in silos but be integrated with ontologies into a semantic layer. Learn about: - The essence and purpose of taxonomies and ontologies in information and knowledge management; - Advantages of semantic layers leveraging organizational taxonomies; and - Components and approaches to creating a semantic layer, including the integration of taxonomies and ontologies

With more memory available, system performance of three Dell devices increased, which can translate to a better user experience Conclusion When your system has plenty of RAM to meet your needs, you can efficiently access the applications and data you need to finish projects and to-do lists without sacrificing time and focus. Our test results show that with more memory available, three Dell PCs delivered better performance and took less time to complete the Procyon Office Productivity benchmark. These advantages translate to users being able to complete workflows more quickly and multitask more easily. Whether you need the mobility of the Latitude 5440, the creative capabilities of the Precision 3470, or the high performance of the OptiPlex Tower Plus 7010, configuring your system with more RAM can help keep processes running smoothly, enabling you to do more without compromising performance.
