The Weekly Notable Startup Funding Report takes us on a trip across various ecosystems in the US, highlighting some of the notable funding activity in the various markets that we track.The notable startup funding rounds for the week ending 6/2/23 featuring funding details for Deep Sentinel, Measurable, Pixxel, and fifteen\ other deals representing $772M in new funding that you need to know about.

Since now you understand how eventual consistency helps microservices, let's discuss a couple of different ways to implement eventual consistency with microservices.Conflict Resolution Mechanisms
Conflict resolution mechanisms are used when there is a high chance of conflicting updates to the same data item in different data stores.

Greeting cards are a very seasonal business.Valentine's Day, Mother's Day, and Father's Day are really big days for us at Thortful, when thousands of concurrent users are on our site and the number of searches per minute multiplies by 30.As an e-marketplace in the B2C space, with small cart sizes, customer loyalty is key to our success.

It is a pessimistic approach to handling long-lasting errors in microservices.This is because certain faults require a variable amount of time to recover, and circuit breaker pattern helps to bring stability and resiliency to the application.Long-lasting faults range in severity from partial loss of connectivity to complete service failure.

The infamous loading indicator.Photo by Mike van den Bos on Unsplash I was at my desk on a lazy Monday morning.Suddenly, an alert appeared on my screen.Our endpoint to show a user's profile info was taking a lot of time to process the requests.I was responsible for that part of the system.I had to do something ... quickly.

In an earlier post, I talked about when it makes sense to use which deployment strategy - Blue-Green, Canary and AB-Testing.In that post, I also added a caution about the development challenges these strategies may entail.In this post let's explore those challenges.If you plan to use AB-Testing to get customer feedback, from which branch of the relevant component's repository are you going to deploy?

This article is a preview of a talk by Greg Arnette for SLOconf 2023 on May 15 - 18.To watch this talk and many more like it, register for free at sloconf.com .Tax season was just a few weeks ago, and that got me thinking about how frustrating it is to get hit with a surprise tax bill and how that can relate to uptime: Configuration sprawl.

Image generated by DALLE, OpenAI The software development industry is constantly evolving and new trends and technologies are emerging every day.One of the most significant trends in recent years is the move towards microservices architecture, which is becoming increasingly popular among organizations.

The term cloud-native has been bandied about for years now but what was once short-hand for a specific type of IT architecture is in danger of becoming yet another meaningless buzzword.The term itself generally refers to IT technologies that are designed to run in a way that makes it simple to spin up and down IT infrastructure resources in the cloud.

While ransomware has been the leading concern for enterprise security teams over the few past years, software vulnerabilities are nipping at its heels.The boom in cloud-based apps and services and increased digitization of work have been a boon for hackers, who are taking advantage of developers' and DevOps teams' attempts to work faster and smarter to keep up with demand.

Understanding software complexity
To understand why distributed tracing is so important, it's helpful to look at the cloud platforms, containerization, and container orchestration that forward-thinking software organizations use to quickly build, scale, and operate business-critical applications.Despite the many advantages of software architectures built on microservices and serverless, the exploding number of components and their diversity in language, operating environment, and ownership creates a huge new burden for teams trying to manage them.

Pure Storage has just announced its partnership between its pioneering Database-Platform-as-a-Service (DBPaaS), Portworx Data Services, and MongoDB Enterprise Advanced, a self-managed database.Pure Storage is responsible for some of the most advanced data storage technology and services worldwide, and its one-of-a-kind partnership with MongoDB may revolutionize the way developers build modern applications.

Hi, internet!I know you are trying to do your best to improve your skills in software development and I am here to give you a niche subject.If you are a backend developer this post is just for you!When we are developing our projects, micro startups or the next big FAANG, we need to do this the right way.

As a management consultant with a PhD in software engineering, I have seen numerous organizations struggle with software architecture decisions that have long-lasting consequences.In a technology-driven advisory, choosing the right architecture for your software system is crucial in ensuring its success.

While dealing with a cloud environment, we come across software, hardware, and network errors which ultimately led to delays, timeouts, and failures in the system.In case of transient failures such as network loss, temporary unavailability of a microservice, timeouts, etc, which are self-recoverable and temporary, we have the option to retry and check if the requests are served.

In the middle of dealing with your services and domains, have you ever been baffled when a team that you even hadn't known existed, reaching out to you and stating a change you made broke their dashboards or workflows making use of a data source that you have possibly never heard of?And even more baffled (like your eyeballs popping out from their sockets 😳) as you see your data on a platform that you are unaware of or other people talking about your internal data representations?

As microservices architecture becomes increasingly popular, it is essential to consider the Law of Demeter when designing and implementing microservices.The Law of Demeter(LoD), also known as the Principle of Least Knowledge, is a design principle that aims to reduce the coupling between objects in a software system.

env0 today announced it has added support for additional infrastructure-as-code (IaC) tools and the Microsoft Azure DevOps platform to its workflow automation and management platform.Fresh from raising an additional $35 million in funding, env0 CEO Ohad Maislish said while Terraform remains the most widely used IaC tool, there are now more organizations using alternatives such as CloudFormation from Amazon Web Services (AWS) along with Pulumi and Terragrunt.

In a microservices architecture, workflows can be classified as short or long-running.Short workflows typically involve a single microservice is completed quickly.Long workflows, also known as sagas[1], involve multiple microservices and can take a long time to complete.The saga coordinator sends a request to the first service to execute the first local transaction.

When I work on a project I differentiate three kinds of tests: unit, integrated, and external.In this post I'll explain how I think about them.FYI unit is the lowest level of tests, integrated is higher, external is even higher.Thinking about the kinds of tests in terms of levels and height comes from the test pyramid, I think.

When deciding to break down a monolithic service into a set of microservices, it's important to evaluate if it is truly necessary based on current and future needs of the application, rather than simply following the trend of using microservices under fomo.While microservices have their own set of advantages, it's important to also consider the challenges and concerns that come with this architecture.

re:Invent How does AWS develop software?It is all about small teams, according to a low-key but revealing session at the re:Invent conference under way in Las Vegas.Under the title "Amazon's DevOps culture," Leo Zhadanovsky, who is Chief Technologist, Education, and Alyssa Lee, Customer Success Lead for AI and ML, described what the company considers its best practices for building, testing, deploying and maintaining "modern applications."

Recently, the Dapr maintainers released V1.10 of Distributed Application Runtime (Dapr), a developer framework for building cloud-native applications, making it easier to run multiple microservices on Kubernetes and interact with external state stores/databases, secret stores, pub/sub-brokers, and other cloud services and self-hosted solutions.

https://unsplash.com/photos/BJHN6Do8kjQAs you know, I've been working more with IoT edge use cases around my career.It was going fine with Azure to date, but when we were re-analyzing the architecture, we found a need for cloud-agnostic microservices instead of cloud-native microservices (more precisely with Azure).

I already worked in many environments, many companies with many monitoring types, each one with a way monitoring, sometimes with poor monitoring, and others with amazing monitoring.But a thing we can't deny is monitoring is essential to a production environment.Imagine a scene where you have many services in which communicate between them, and someone is unavailable, or is throwing exceptions for some reason - how will you ensure that you know about it?

Software quality is a critical factor in the development and deployment of successful applications.It directly impacts a range of business outcomes, including maintenance, time to market, and total cost of ownership.As a management consultant with a PhD in software engineering, I have seen the impact of software quality firsthand and would like to share my insights on the topic.

If you are working with a microservices architecture you may have encountered the need of duplicating a large table between different services.In theory, this result can be obtained using event sourcing.You publish all the transitions of your entity in a topic, following the order of modifications, and then you can reconstruct the state of that entity in a different service.

VMware has released Spring Cloud 2022.0.0, codenamed Kilburn, featuring updates to many of the Spring Cloud sub-projects.Built upon Spring Framework 6 and Spring Boot 3, introduced in November 2022, Spring Cloud is aligned with Java 17 and compatible with Jakarta EE 9.This release supports Ahead of Time (AOT) compilation and the creation native images with GraalVM.Spring Cloud Commons now supports weighted load-balancing by configuring the property, spring.cloud.loadbalancer.configurations, as .

Whether you've heard it anecdotally or read the research, pricing and billing can be a barrier to observability.Software pricing and billing can be complex; that complexity can be further exacerbated when trying to compare the costs of different observability vendors with different pricing and billing models.

Microservices architecture has become the new norm for large-scale applications.Because it has more advantages compared to traditional monolithic architecture.However, microservices also come with several challenges.One such challenge is preventing cascading failures.For example, network or service failure in one microservice can quickly cascade into other services and cause a system-wide failure.

Couldn't attend Amazic World Amsterdam?Just watch this recap with Roald Ruchti, Regional Sales Director at Sysdig, explaining how they help to monitor and secure containers, cloud environments and traditional workloads.Sysdig gives companies, who are in their DevOps transition and adopting microservices, the right visibility to act upon security threats.

Key Takeaways


     Handling breaking changes in a blue-green deployment requires upfront planning and good architectural choices
     One approach to handling breaking changes is to dependency order the releases, however, this can complicate the release process
     Ideally, blue-green deployments in microservice architectures can make use of API versioning to ensure the requests are routed to the correct version
     Attempting to tack-on blue-green releases into an architecture that doesn't support it can lead to more complicated and fragile deployments
     While a microservice architecture has its benefits, it can make deployments more complicated.

The Rust programming language has gained mainstream adoption in the past several years.It is consistently ranked as the most beloved programming language by developers and has been accepted into the Linux kernel.Rust enables developers to write correct and memory-safe programs that are as fast and as small as C programs.

If you ever wanted to understand how an AWS multi-account strategy works, you're in the right place!In this blog post, we'll explore a bottom-up approach where we'll see how to secure your single AWS account and then move to a multi-account organization with a fun take.So, first of all, we need to understand what is an AWS account and let's deep dive into the topic with a definition:

💡 An AWS account acts as a resource container and resource isolation boundary

The two essential keywords here are container and isolation boundary, and I don't know about you, but to me, they both contribute to forming a pretty clear image:
