Introducing Azure Well-Architected Framework for Internet of Things (IoT)

Internet of Things (IoT) projects are high in complexity, and this complexity can increase substantially over time. While IoT is widely adopted in organizations, only a quarter of those IoT projects are in use, while many fail in the proof-of-concept stage. Companies cite a lack of knowledge and technical complexity as many of the challenges preventing them from using IoT more and developing new IoT solutions.

Feathr: LinkedIn’s feature store is now available on Azure

Developing a feature store from scratch takes time, and it takes much more time to make it stable, scalable, and user-friendly. Feathr is the feature store that has been used in production and battle-tested in LinkedIn for over 6 years, serving all the LinkedIn machine learning feature platform with thousands of features in production.

At Microsoft, the LinkedIn team and the Azure team have worked very closely to open source Feathr, make it extensible, and build native integration with Azure. It’s available in this GitHub repository and you can read more about Feathr on the LinkedIn Engineering Blog.

Optimize your cloud investment with Azure Reservations

Continuous cost optimization can take place at all stages of an Azure workload’s lifecycle, but your Azure subscription provides a very effective benefit to further optimize your investment when you are ready to deploy that workload.

For cloud workloads with consistent resource usage, you can buy reserved instances at a significant discount and reduce your workload costs by up to 72 percent compared to pay-as-you-go prices. Azure Reservations can be obtained by committing to one-year or three-year plans for virtual machines, Azure Blob storage or Azure Data Lake Storage Gen2, SQL Database compute capacity, Azure Cosmos DB throughput, and other Azure resources.

When you can predict and commit to needed capacity, it gives us visibility into your resource requirements in advance, allowing us to be more efficient in our operations. We can then pass the savings on to you. This benefit applies to both Windows and Linux virtual machines (VMs).

In addition, you now can combine the cost savings of reserved instances with the added Azure Hybrid Benefit when running on-premises and Azure workloads to save up to 80 percent over pay-as-you-go pricing.

Public preview: Health probes support in Azure Container Apps

Azure Container Apps, a service for building and deploying modern applications and microservices using serverless containers, now supports health probes to provide developers more control over their applications.

Readiness, liveness, and startup probes are now available over HTTP(S) and TCP protocols.

Check out the article: Public preview: Health probes support in Azure Container Apps


General availability: Azure Cosmos DB autoscale RU/s entry point is 4x lower

With Azure Cosmos DB autoscale, you can now set a scale range of 100 - 1000 RU/s, which is 4x lower than the previous minimum scale range of 400 - 4000 RU/s. Autoscale automatically scales the throughput of your database or container within a specified range, removing the need for manual capacity management. For smaller workloads that do not require high throughput, setting the new scale range can make autoscale up to 4x lower in cost, while still providing the ability to scale-up to handle spikes of traffic. 

If you’re using an Azure Cosmos DB free tier account, you can use autoscale in your free tier account at no cost. By creating a shared throughput database with autoscale (100 – 1000 RU/s), you can have up to 25 containers sharing the overall throughput for free.

Public preview: Azure Monitor activity log insights

The dashboards present data about which users or services performed activities in the subscription and the activities' status.

Activity logs you send to a Log Analytics workspace are stored in a table called AzureActivity.

Activity log insights are a curated Log Analytics workbook with dashboards that visualize the data in the AzureActivity table. For example, which administrators deleted, updated or created resources, and whether the activities failed or succeeded.

Inside the making of the Azure SDK management libraries

As a cloud native developer, which types of developer experiences do you care about the most? Interacting with cloud resources in your app is certainly at the top of your experiences list—whether sending a message to an Azure Service Bus endpoint or creating new VM instances to carry heavier workloads. You can use a cloud SDK, like the Azure SDK, for all these cloud service interactions, but how is the Azure SDK generated? What’s the difference between a cloud SDK and a traditional SDK? Let’s start our journey!

Introducing Central Package Management

Dependency management is a core feature of NuGet. Managing dependencies for a single project can be easy. Managing dependencies for multi-project solutions can prove to be difficult as they start to scale in size and complexity. In situations where you manage common dependencies for many different projects, you can leverage NuGet’s central package management features to do all of this from the ease of a single location.

Historically, NuGet package dependencies have been managed in two main locations:

  • packages.config – An XML file used in older project types to maintain the list of packages referenced by the project.
  • <PackageReference /> – An XML element used in new project types that manages NuGet dependencies directly within project files.

Starting with NuGet 6.2, you can centrally manage your dependencies in your projects with the addition of a Directory.Packages.props file.

The feature is available across all NuGet integrated tooling.

Why you should always Cleanup Side Effects in React useEffect and How to Cleanup

Well, because cleaning up is generally a good thing :)

Side effects happen a lot in React applications (in web applications generally. These effects include making asynchronous API calls, updating the DOM, creating sockets, etc. These side effects can happen when a button is clicked, when a form is submitted, or when a component mounts.

The useEffect hook in React gave functional components the power to do stuff when a component mounts or when some props or state changes. This hook also allows you to cleanup when the component unmounts.

What are side effects cleanups? Why should you cleanup them? How do you cleanup them?

In this article, I'll answer these questions, and hopefully, you will get a better hang of the useEffect hook at the end of it.

React components composition: how to get it right

One of the most interesting and challenging things in React is not mastering some advanced techniques for state management or how to use Context properly. More complicated to get right is how and when we should separate our code into independent components and how to compose them properly. I often see developers falling into two traps: either they are not extracting them soon enough, and end up with huge components “monoliths” that do way too many things at the same time, and that are a nightmare to maintain. Or, especially after they have been burned a few times by the previous pattern, they extract components way too early, which results in a complicated combination of multiple abstractions, over-engineered code and again, a nightmare to maintain.

What I want to do today, is to offer a few techniques and rules, that could help identify when and how to extract components on time and how not to fall into an over-engineering trap. But first, let’s refresh some basics: what is composition and which compositions patterns are available to us?

An Overlooked Factor For Performance Optimization In React

Many people, including me, sometimes like to seek out simple answers to problems they are faced with. It is relatively easy to arrive at a generic conclusion for most cases – we often forget or intentionally leave out edge cases. In the context of performance optimization in React, one of these edge cases is the position of your component in the component tree.

Removal Of Implicit Children

With React 18 we have the opportunity in @types/react to fix long-standing issues we had to deal with for a long time. We originally wanted to fix these in React 17, but held off because React 17 was a big step in enabling gradual migration. One of these changes is removal of implicit children in React.FunctionComponent types. I’ll try to explain why we want to make this change and how you can ease migration.

The Scoop: Inside the Longest Atlassian Outage of All Time

We are in the middle of the longest outage Atlassian has ever had. Close to 400 companies and anywhere from 50,000 to 800,000 users had no access to JIRA, Confluence, OpsGenie, JIRA Status page, and other Atlassian Cloud services.

The outage is on its 9th day, having started on Monday, 4th of April. Atlassian estimates many impacted customers will be unable to access their services for another two weeks. At the time of writing, 45% of companies have seen their access restored. Companies impacted I talked with were as large as 4,000 seats and the smallest company impacted I talked with had 150 seats.

Should you prioritize infrastructure costs?

Before diving into the mechanics of managing infrastructure costs, the first question to answer is whether it’s a valuable use of organizational time to make your current infrastructure spend more efficient. How you think about this will vary a bit depending on whether your company is early-stage, prioritizing growth or profitability.

Architecture Patterns: Caching (Part-1)

Performance has always been a key feature of technical systems. Today on the internet, sub-second latencies are the norm. It costs companies money if their pages load slowly because potential customers won’t wait longer than that. On the other hand, there is more and more data from many different sources which have to be loaded into a rich user experience (think of the number of things going on a typical FB page). This data gathering problem is further exacerbated by the trend towards microservices.

Given all this, how are we to build super-fast systems?

How Netflix Content Engineering makes a federated graph searchable

Over the past few years Content Engineering at Netflix has been transitioning many of its services to use a federated GraphQL platform. GraphQL federation enables domain teams to independently build and operate their own Domain Graph Services (DGS) and, at the same time, connect their domain with other domains in a unified GraphQL schema exposed by a federated gateway.
