How to Deal with Service Failures

Sep 18, 2019

It’s simple, really — services call other services and they take actions based on the responses from those services. Sometimes, that action is a success, sometimes it’s a failure. But whether it is a success or a failure depends on if the interaction meets certain requirements. In particular, the response must be predictable, understandable and reasonable for the given situation. This is important so that the service reading the response can make appropriate decisions and not propagate garbage results. When a service gets a response it does not understand, it can take actions based on the garbage response and those actions can have dangerous side effects to your service and your application.

5 tips to choose a serverless vendor

Published July 22, 2019

The global serverless architecture market shows no signs of slowing down with multiple vendors offering their services in a fast-growing arena. AWS, Microsoft, Google, Alibaba, Rackspace, IBM, Oracle, and CA Technologies are just a few industry names investing heavily in the serverless space. It’s no wonder that vendors are scrambling for a big slice of the pie: According to KBV Research, the global serverless architecture market is expected to hit US$14 billion by 2024, increasing at a growth rate of 23.4 per cent CAGR during the forecast period.  In Australia, “serverless” is all the rage at the moment with multiple vendors rushing to claim pole position where functions-as-a-service, or FaaS, is fast gaining traction. It’s critical to note that while developing applications using the FaaS model is a way of achieving a serverless environment, there is confusion over how to choose the right vendor. Here are five considerations on how to choose a FaaS-serverless vendor to meet your organisational needs.

4 factors to ruin your serverless migration

Published May 23, 2019

As more and more companies embark on their digital transformation journey, organisations need to upgrade and evolve their infrastructure technology to maintain a competitive edge. The promise of serverless is to allow organisations to focus on their application and not worry about infrastructure, which includes buying, scaling, and securing infrastructure to run their applications. As I’ve previously discussed, it’s critical that serverless is chosen for the right kind of task. It’s perfect for handling short tasked based jobs that take a relatively small period of time to execute, but it’s less useful for long running tasks or for complex tasks. However, even with a well-considered strategy and a solid budget, the migration to serverless can go awry.

3 ways serverless is a game changer

Published May 16, 2019

The dream of serverless is to enable companies to focus on making their application work, rather than getting tied up with managing infrastructure. Serverless is actually a misnomer: there are still servers, but your cloud provider runs them and dynamically manages the allocation of machine resources. The idea is that a company then only needs to focus on its apps, not its infrastructure. One question that gets asked frequently is which companies are best suited to serverless, in terms of the benefits they will see? However, determining success is actually less about the type of organisation that should consider serverless and more about the type of computing that is best used for serverless and whether your organisation needs it. If serverless is right for your organisation, these are the top three benefits you can expect to realise.

The Four Pitfalls of Cloud Migration

Jul 23, 2018

Migrating to the cloud is easy, right? What could possibly go wrong? There are at least four things I can think of. Often, when we begin a cloud migration, we come in with lofty expectations. As the migration progresses, however, we often find that moving to the cloud isn’t necessarily as easy as we would like it to be - or as easy as we were led to believe it would be. Sometimes, the cloud doesn’t meet our expectations. Promises we’ve been given may not hold true. Promises we’ve made to our stakeholders can turn out to be impossible to keep. Migrating to the cloud is not necessarily the slam dunk we expected it to be.

The Great Serverless Debate

Jul 11, 2018

The concept of “serverless” is on the minds of many developers and operations teams these days. The technology is definitely hot, but is serverless really ready for prime time in production environments? To find out, we invited a pair of New Relic experts, senior director of strategic architecture Lee Atchison and developer advocate Clay Smith, back to the show to debate the issue. Listen in to the podcast on New Relic’s Modern Software Podcast, below or on iTunes: You can also read an edited transcript of the discussion on the New Relic Blog.

3 common mistakes companies make when adopting cloud

May 24, 2018

Cloud computing is mainstream. That’s a fact. Chances are if your company isn’t already extensively using the cloud, it is planning on doing so in the very near future. But be careful. There are many mistakes that companies new to the cloud make when they begin looking into cloud adoption. Here are three of the main ones.

The Future of Kubernetes is not Lambda, it's Containers

Apr 30, 2018

I wrote not that long ago (see article in Diginomica) that the future of serverless is not Lambda, but is technologies such as AWS Fargate. I truly believe this is. Lambda is very useful for some kinds of computing needs, but it is not suitable as a general serverless solution to replace standard programming methodologies for building services and systems.

Forget AWS Lambda, so long Kubernetes – this is the future of serverless

Apr 23, 2018

Last year I wrote an article on what serverless computing is all about. In that article, I described that while serverless computing doesn’t remove servers, it moves the management of servers to the cloud computing provider, away from your development and IT organization. It removes complexity from application management and enables easier and more significant scaling by sharing server resources across a larger set of consumers. But last year, when you said ‘serverless computing’, you were almost exclusively referring to Function-as-a-Service (FaaS) technologies such as AWS Lambda, Microsoft Azure Functions, and Google Cloud Functions. While there are other serverless technologies – such as serverless data stores and databases – these functional computing services were usually what you meant when you were referring to ‘serverless computing’.

DevOps Reading List: Top 30 Best DevOps Books You Should Read In 2018

Apr 3, 2018

The #1 book on their list is “Architecting for Scale” book by Lee Atchison. As the article says:

"The first one on our DevOps reading list is Architecting for Scale. It is an excellent book to understand real-world paradigms for scaling and managing critical applications. This book covers 5 different elements: availability, risk management, services and microservices, scaling applications and cloud services. This book can be called a practical guide as well, it shows how to prevent an application from becoming slow, inconsistent, or downright unavailable as it grows. Also, in this book the word “Scaling” is explained very well as it is not just about handling more users; it’s also about managing risk and ensuring availability."

Multi-Tenant Cloud vs. Single-Tenant Cloud: An Important Choice

Feb 28, 2018

Whenever we discuss cloud adoption with enterprise companies curious about making the move, one of the first questions is, which is better: public cloud or private cloud? Cloud adopters want to know which approach is most likely to give them better performance, greater flexibility, stronger security, and lowest cost to operate. While these are important requirements,  they miss a critical issue: So you want to share your cloud with others? If you’re working towards an effective cloud adoption strategy, you’d be wise to consider whether you want a multi-tenant or single-tenant cloud offering.

Modern Software Podcast - Multi-Cloud Adoption

Feb 26, 2018

That’s just one key takeaway from the latest episode of the New Relic Modern Software Podcast, which delves into the complex world of running—and monitoring—applications in multi-cloud environments.

The 2018 Pivot For Dynamic Apps, DevOps: Live Deployment Monitoring Takes Center Stage Away From Container Orchestration

Feb 12, 2018

“The yin-yang of dynamic apps and DevOps may come into a new balance in 2018. Container orchestration will be less important, while monitoring live deployments will become the crucial focus. This shift comes in large part due to big steps in Amazon Web Services, says Lee Atchison, senior director of strategic architecture at New Relic. IDN explores. “ Read this interview with Lee Atchison on idevnews.

AWS Lambda v Amazon ECS — Two Paths To One Goal, Which Is Best?

Jul 5, 2017

Launched in parallel two and a half years ago by Amazon Web Services (AWS), AWS Lambda and Amazon EC2 Container Service (ECS) are two distinct services that each offer a new, leaner way of accessing compute resources. Amazon ECS lets developers tap into container technology on a pay-as-you-go basis. AWS Lambda offers what is often known as ‘serverless’ computing, or function-as-a-service — the ability to access specific functions, again on pay-as-you-go terms.

Building Right-Sized Application Services: The Goldilocks Calculation

Dec 21, 2016

In the world of applications, services are standalone components that, when connected and working together, create an application that performs some business purpose. But services come in a wide variety of sizes, from tiny, super-specialized microservices up to services big and complete enough to form their own monolithic applications.

Visibility into the Migration From Static to Dynamic Infrastructure [Video]

Sep 14, 2016

When I look back at my career over the last 30 years, it’s amazing to see how much the world has changed when it comes to building, running, and managing software. At my first job, for example, our company was trying to reduce its development cycle down to less than a year. Nowadays with cloud architectures we’re seeing development cycles of just weeks, days, or even hours. But that’s not to say that all cloud environments are dynamic and rapidly changing.

Why I Wrote the Book on ‘Architecting for Scale’

Jul 25, 2016

As applications grow, two things begin to happen: they become significantly more complicated (and hence brittle), and they handle significantly larger traffic volume (which more novel and complex mechanisms manage). This can lead to a death spiral for an application, with users experiencing brownouts, blackouts, and other quality-of-service and availability problems. “But your customers don’t care. They just want to use your application to do the job they expect it to do. If your application is down, slow, or inconsistent, customers will simply abandon it and seek out competitors that can handle their business. That’s how my new book, Architecting for Scale: High Availability for Your Growing Applications, begins.

Day at Fenway

Jun 1, 2016

I arrived at the hotel, a typical Residence Inn, and checked in. “You have a view of Fenway from your room”. Oh, that’s cool. I went to the room, looked outside, and there she was, the green industrial looking complex that is Fenway Park. It didn’t look all that special from where I was. That would change. I arrived early in the day, and didn’t “officially” have any scheduled events until the next day, but I had to prepare what I was going to do the following day, and I’m sure I would be meeting up with some of the other New Relic and MLB folks for dinner later. But, that still left me time to look around.

An updated copy of my book, Architecting for Scale, published by O’Reilly Media, is available for download. This is the second version under the early release program. The full book is scheduled to be released in May.

Scaling with Availability

Jan 14, 2016

One of the most important topics in architecting for scalable systems is availability. While there are some companies and some services where a certain amount of downtime is reasonable and expected, most businesses cannot have any downtime at all without it impacting their customer’s satisfaction, and ultimately their company’s bottom line. How do you keep your customers happily using your service and keep your company’s revenue coming in? You keep your service operational as much as possible. There is a direct and meaningful correlation between system availability, and customer satisfaction.

Why Use Microservices?

Jan 6, 2016

Traditionally, software companies created large, monolithic applications. The single monolith encompasses all business activities for a single application. As the company grew, so did the monolith. In this model, implementing an improved piece of business functionality requires developers to make changes within the single application, often with many other developers attempting to make changes to the same single application. Developers can easily step on each other’s toes and make conflicting changes that result in problems and outages. Development organizations get stuck in the muck, and applications slow down and become unreliable. The companies, as a result, end up losing customers and money. The muck is not inevitable, you can build and rearchitect your application to scale with your company, not against it.
