It's what makes them exciting. They have to change fast. Now I need to join and query graph seven different microservices, but each one has its own data and its own query. I do believe that it was evolutionary. Continuing the analyzing architecture lessons, Mark Richards describes some macro architecture analysis techniques specific to Microservices. It's gonna take four miles to turn that ship around now. Companies jumped in before fully understanding SOA’s advantages and disadvantages, and struggled to make this complex architecture work. But you know, there's two that are really coming to mind, in my opinion at the very forefront of those. While some companies experience success with microservices, most companies experience pain, cost overruns, and failed initiatives while designing and implementing this incredibly complex architecture style. I make the joke, David, by the way that I usually say, "Oh, so you're using microservices. "Well, you have a lot of cost overruns and high attrition." Businesses are learning how to change business processes quickly, but then it hits IT and everything stalls out for months, years, crickets chirping. Microservices was the very first architecture style that came out that required us to consider data as part of the architectural design. When we start talking about cohesion and coupling and connascence, and all these technical details about structuring our code and our services, that's the structural aspect. I miss the feedback. "No, let's do it this way now." And these are free. We had continuous integration and that was a good first step, but continuous deployment, when Dave Farley and Jez Humble came out with that book, was just remarkable.I mean, this, this finally gave us the answers on how to effectively deploy software. I can infer a couple of things about your environment." Levels of fault tolerance done right is fantastic. "I'll do all of our stuff in microservices or serverless." It was a thought. Goodreads helps you keep track of books you want to read. But microservices - and I have been doing microservices for a little over six years now, almost devoting my whole career to it at this point for the past six years - I have also seen the revolutionary aspects of microservices. MR: Well, the single place where everybody can go, the nice thing is my website Developertoarchitect.com and that's T-O so the movement from, think of, "I'm a developer. I think the other thing that we have learned over the course of, I'll say six years or seven years, is quite frankly, not every portion of an application has to be microservices.We can form hybrids. And really that first one is, the first hurdle that I usually see is all about service granularity.How big should a service be? That was really the first catalyst from the evolutionary standpoint, in my opinion. Man, try to turn a monolith. And thank you so much for having me on this podcast. Well, in the monolith that was an SQL Join across seven tables. DB: Can you share some of the weaknesses you've discovered in microservices? Yeah, yeah, yeah. MR: All right. We can have portions of our applications, embracing the microservices, architecture and portions being mini monoliths, or even service-based architecture. No, we can still have this impedance mismatch, these two camps of architects and data architects, and they somehow combine the poor developers, try to glue them together. Refresh and try again. Mark Richards is an experienced hands-on software architect involved in the architecture, design, and implementation of Microservices Architectures, Service Oriented Architectures, and distributed systems in J2EE and other technologies. And that’s data latency. There are solutions to these hurdles and problems. And I still do maintain by the way, David, that there are no best practices in the structural aspect. Fantastic. KM: I'm personally having coffee because it's seven o'clock in the morning here in the Philippines. I miss seeing people's expressions and collaborating on this stuff. They’re like, "How'd you know?" I'll tell you though, David, I do really, really, really miss the in-person experience. That worked as well. All Rights Reserved. And that was the first law. Now we never really had to before, you know, we talked to them, communicated, but not collaborated. How do you distinguish between structure and process? One of the things that is near and dear to my heart is architectural change. It makes my life much easier now that I can talk about addressing the Reach-in Reporting Anti Pattern at work. It's like, "How did you know?". MR: This, I get excited about this. David, what a great analogy, because you're right in any revolution there is a lot of pain. Is there an easy answer to it? About Mark Richards Independent Software Architect, Author of Fundamentals of Software Architecture. We really didn't have that live bulk feedback that you get from these conferences and making these statements. To see what your friends thought of this book. I can't tell you and won't tell you the definitely the clients and the number of clients that I have been in over the past six years that effectively have created a large, distributed, big ball of mud or what some of my clients call, "We have a distributed monolith," and I will step back and say, "Wait a minute, let me guess. Weaknesses. So that's why performance, again, it sounds surprising doesn't it? How are you doing, David? David, this is a matter of dropping in new microservices or adopting existing ones that are needed. And I like to do keynotes in two forms - one is to inspire; the other is to incite. It's taking a step back and taking a more cautious approach to saying, "Should we be using microservices?" Like you said, you know, it is a revolution and people are doing it for a reason. It's a way of recording and documenting the architecture, but recording the "how", or I'm sorry, recording the "why". And what if we all have a bunch of large monolithic applications that didn't work? What's your take on where microservice is going, how the functions of the service fit into all this? And there's a lot of hidden aspects that are abstracted from us now in a lot of the frameworks and tools and the cautionary tale is really understanding embracing those but understanding those abstractions. I run out of memory very quickly. Microservices has given us this. Yes, in fact, both Neal Ford and I did consider the techniques and soft skills aspects as well. We've been beaten over the head about having to pay attention to data. That's how you get an effective system, but is it required? It started hitting me hard, late October, and it's hitting me hard now. MR: You're right, David, and this is one of those "gotchas" that you end up with when you start not with maybe three or four services, but once you really start in earnest developing dozens to hundreds, to even thousands of services. MR: Boy, Kevin, did I get into a lot of heated debates with that comment. DB: Alright I don’t want to scare people away from microservices. Sure, our payment service, that we accept five different payment types for our processing - should that be one service or five? David, this is awesome stuff. If this was a book, I think I'd give it less stars, but since it is just a short paper, it feels alright -- for a book, longer content and how to implement the corrects would be nicer. We as architects have to collaborate with developers or it won't work. Concise and easy to follow overview. Not a book per se, but a paper about the tendencies that lead to microservices to fail. The fundamentals of software architecture and microservices with Mark Richards. Always collaborating, communicating with a stakeholder. And these are companies that I work with, companies I'm in trainings or conferences that I do. What are the challenges that they're facing when they're implementing microservices? So how can I say and claim that that's a best practice?So we did analyze a lot of the process aspects, however Neal and I fed off each other. One is network latency. Explains each problem in a very clear way and gives almost real life examples. I see where my mistake is.". MR: Yeah. Every other Monday, David, I do something called "Software Architecture Monday," which is a free video for 10 minutes. Mark is a GSAS speaker, Apium Academy Professor and an experienced, hands-on software architect involved in the architecture, design, and implementation of microservices architectures, service-oriented architectures, and distributed systems in a variety of technologies. He's been in the software industry since 1983 and has significant experience and expertise in application, integration, and enterprise architecture. The other place David, that I really see microservices going is more towards hybrid architectures. And you know, "I've been using them for years and they add value" and blah, blah, blah.And so it was really valuable because there were valid points, valid discussion, and got the community discussing the whole concept and value of connectors and where the industry might be leading and it brought out a discussion. MR: So, there's so many, many good reasons why this is on the hype curve. DB: Mark, you said it incited a response as intended. When we talk about the ease of auto-scaling elasticity, which used to take me four months to architect is a switch that I set in Kubernetes now. Remember when service-oriented architecture (SOA) was all the rage? There you can see upcoming events. Five stars for Agility, Agility being defined as the ability to respond quickly to change. by O'Reilly. I would have to say, David, both. You mentioned that you enjoy the conferences. Get the latest news delivered to your inbox. And let me explain why I'm saying both. MR: Oh, wow. I'd be interested to know your perspective of where it's all going and how potentially functions as a service fit into this because, you know, functions as a service and not really the bounded context is perhaps not well-defined. You cannot query that table." And I do believe that we did, and that's what I love so much about microservices. And these are some of the real major hurdles and challenges. This is the part where not all data can be broken apart. So let's move on to architecture itself. Understanding it is complex and it's not a silver bullet and maybe we shouldn't use it.And this gets me excited because I see that learning happening as teams and companies are getting and gaining these lessons learned. Just a moment while we sign you in to your Goodreads account. What's next? Where does it work? I applaud you for doing this. Microservices holds the promise of being able to address some of the problems associated with large, complex SOA architec‐ tures as well as the problems found with big, over-bloated mono‐ And so those are some of the main ones. "And let me give you a couple of examples where this came from, and then I can kind of qualify it for you. I think, David, is the fact that we make these statements and especially if they incite something or they're a little bit controversial, what it does promote is conversation. But a lot of times I can't, I have to do a workflow. MR: Structure is when we start applying technical aspects to how our code, our source code is organized. And one of the good ways of really getting an understanding and trying to define software architecture is to think about it, really, as two different aspects - architecture, the structure - and that's more of the technical architecture. Microservices has finally beat us over. MR: The major objections were, in fact, it was to bullet a statement that in fact there are best practices in architecture. Mark Richards is an experienced hands-on software architect involved in the architecture, design, and implementation of microservices architectures, service-oriented architectures, and distributed systems. And so that's where kind of, I stepped a little over the line there and like I said, I'm glad I did. And this one seemed to actually do both. It was all those lessons learned and doing things the wrong way and saying, "Yikes that was not good, was it?" And this was before microservices even existed.And it was hard. "However, I will concur within another aspect of software architecture, which is architecture, the process, there are in fact, some best practices. Did not know that there were transacted messaging even when using queues. Mark Richards is an experienced hands-on software architect involved in the architecture, design, and implementation of microservices architectures, service-oriented architectures, and distributed systems. In addition to hands-on consulting, he's also a conference speaker and trainer, having spoken to hundreds of conferences and user groups around the world on a variety of enterprise-related technical topics.And he can now proudly add Coding Over Cocktails to one of those speaking engagements. As a matter of fact, that was during the keynote at O'Reilly's Software Architecture Conference last February - almost a year ago. The tools are making microservices and frameworks a lot easier, a lot easier to manage, a lot easier to deploy and also to even create, but the devil's in the details. Microservices Lessons. Super high levels of scalability. or was that a distinction you made after you stirred the pot and got all this debate going? Top 10 Cloud Solution Provider APAC - 2019, Top 10 Digital Transformation Solution Companies - 2020. It's been a pleasure. Decomposing data is extremely difficult. There's a good best practice. I love architecture decision records. There's nothing like that face-to-face contact is there. So how can people stay in touch with you and hear your voice and keep up today with what your thoughts are? And record or remediation by those public services, managed services, making that process easier, you know, if you were the public cloud provider. It depends on the time of the day. Welcome back. 78 New Paperbacks for Your Summer Reading List. This is perhaps aside from service granularity, probably the biggest challenge, at least in my experience at clients' sites that I've been at and helping, it's really dealing with data and breaking apart data. I want to be an architect." If you need to knowif microservices is for you, or you're a victim of the hype, you better read this small book, that sumarizes all the pros and cons, and signal all the potential problems you could face if you (or your team) start working with microservices. Let me give you a really good one; the use of architecture decision records. I started experimenting with DevOps way back when I was an employee with IBM, and this goes back into, oh gosh, the late nineties, early two thousands. Let's go into that space. Readers are able to know basic concerns and options from architects and developers viewpoint. DevOps was a neat idea. The other aspect - revolutionary - that I kind of saw that was kind of the main one was really this data piece, but also the other revolutionary aspect of microservices was this real bridging of collaboration. Mark Richards is an experienced, hands-on software architect involved in the architecture, design, and implementation of microservices architectures, service-oriented architectures, and distributed systems. The first was this whole idea of continuous deployment. So what are some of the reasons? DB: Got it. DB: You've seen this out of people's own experience. Thinking about microservices or doing it will either be nodding their head or saying, "Oh, I didn't think of that." I think this, these concepts really formed microservices. July 27th 2016 MR: You know what, David, this is what I absolutely, positively love about conferences and what I miss so much about speaking at them live, because without doing this, you don't get the feedback. Before getting on board microservices architecture, it's better to read. Today, we’re poised to repeat this same experience with microservices—only this time we’re prepared. It's interesting to see. The connector is dead between application integration and direct API to API integration, by passing connectors is the future. Start by marking “Microservices AntiPatterns and Pitfalls” as Want to Read: Error rating book. That was pretty fast, about seven to eight milliseconds. Software Architecture Monday with Mark Richards is a free bi-weekly software architecture lesson containing a short video about some aspect of software architecture. Not many, but you know, the other weakness of microservices is cost and complexity, the two big Cs. It’s scalability at a function level. And I will qualify to say, within the structural aspects of software architecture, there are no best practices because every environment, every situation, is different and you can't say, "Oh, you should always do this. Today Microservices is taking the IT industry by storm as the go-to architecture style used to develop highly scalable and modular appli‐ cations. You can't make these statements because of our first law of software architecture. There's three reasons. Mark Richards is an experienced hands-on software architect involved in the architecture, design, and implementation of microservices architectures, service-oriented architectures, and distributed systems. You've written a lot about microservices. DB: My thought is when you came up with this statement, "There are no best practices…", had you distinguished between "There are no best practices in structural design as opposed to process design?" Well, if I'm using an in-memory data cache, for example, or an in-memory data grid through replicated caching, and I've got a 500 KB cache and I all of a sudden spin up 40 instances guess what happens? ", I'm like, "Ooh, yeah." DB: Not many people would expect that outcome. It's interesting to see how that's being driven down from large enterprise to smaller enterprise, because there is some complexity associated with microservices and, and so, smaller enterprises perhaps are not as well equipped to deploy it, but it's getting pervasive. And that's where the learning comes from, in my opinion. So I had to soften my tone a little bit on that and really focus it more on the structural aspects because I do concur that there are in fact, the best practices in the process of creating architectures. We tend to forget that when we're invoking another service, that's necessarily a remote service and we are going through the network and there is network latency that we didn't have before. And it incited a similar sort of response because it was almost an opinion piece, right? Why are there no best practices in software architecture? It's been so much fun talking with you about these ideas. Not a book per se, but a paper about the tendencies that lead to microservices to fail. And so let's bundle it into the service, you know, and okay, well, we’re starting to build a monolithic app again and now they always recommend the concept of a microservice itself. We're not talking a little tiny speed boat. It’s like, "Wait a minute, no. I could probably spend a half an hour actually going through examples where everything's a trade-off. We’d love your help. Why is microservices so incredibly popular? And that's really the key. Lively conversations, let's put it that way, David.Service granularity is hard. So, that's what I mean about the devil in the details. Mark Richards: Hi Kevin! Well, actually, we've touched on some of them just in the hurdles itself.
