"Simplifying the Complex: Effective Management of Large-Scale PHP Projects", Andrii Yatsenko

Aug 12, 20230 likes315 views

Developing and managing large projects can become a challenge for developers. This presentation will show how to overcome these challenges, using the example of one of the largest open-source PHP projects. We will discuss approaches to code organization, coding standards, effective tools, as well as the role of code review and testing. We won't forget about design patterns either.

Imagine that you've been given an old project, a Food Delivery app, with the backend written in Laravel 8 and PHP 8.0. The web and mobile interfaces communicate with the backend through an API, but it's currently performing poorly with an average response time of 600ms. The product owner has requested you to optimize the performance and wonders if it's possible to reduce it by a factor of 10. What would you do? Topics to be Covered: Nginx Cache Rememberable package Redis Cache Queues: Redis/SQS Horizon Octane: Swoole / Roadrunner Upgrading PHP and Laravel While you may be familiar with most of these points and possibly already using them, the focus will be on ensuring that you're using them correctly and effectively. In a real-world example, I will demonstrate how we managed to reduce average response times by 10 times. We'll explore what's hidden under Laravel's package magic and discuss ways to mitigate the negative impact on project performance. By the end of this performance optimization session, you will not only have improved your performance but also gained a deeper understanding of how to utilize the Laravel framework more efficiently.

��

Designing and implementing a scalable and reliable message-sending service may seem like a challenging and time-consuming task. However, let's explore some key points of implementation in .NET that will help us achieve the desired level of quality and avoid unexpected obstacles. To accomplish this, we will: Explore of some features of the .NET Confluent Kafka driver. Examine real-life use cases of utilizing .NET channels as an InProc Pub/Sub mechanism to enhance application performance. Discuss the usage of Minimal API and understand its limitations. Compare gRPC streaming with HTTP and determine which option is more suitable for our specific scenario.

"How we optimized our product without paid solutions", Dmytro NemeshFwdays

��

The story of how we refused third-party DevOps services and took over all services ourselves. In the process, we made a complete revision of the infrastructure, added new monitoring and profiling tools on production. Action algorithms were built based on tools: Graylog, Grafana, influxDB, Pyroscope, Prometheus. As a result, the utilization of resources decreased by two times, and responses to key APIs were accelerated. During the talk, I'll cover what problems we found, how exactly we improved the metrics, and how we got to swoole.

"gRPC-based microservice communication: pros and cons based on our experience...Fwdays

��

In modern microservice architectures, selecting the right protocol for interaction between microservices plays a crucial role in the overall performance and reliability of the system. In my presentation, I will share our migration experience from the traditional HTTP API to gRPC, including the motivations behind this decision and the challenges encountered during the migration process. We will explore the advantages and limitations that gRPC brought to our system and the results of an experiment where we compared the performance of the protocols. Through real examples, we will check some use cases where migration to gRPC is a great solution and discuss scenarios where this approach might be less effective.

We at MacPaw practice the approach of service teams. And as one of such teams, the responsibility for delivering software across various environments, from testing to production, falls on our shoulders. In this presentation, I will explain how we are trying to standardize our approach to software delivery in environments with diverse tech stacks and development approaches. The presentation will cover methods such as GitOps, dynamic environments, and event-based software delivery.

Architecture in 2013 comes from scratch, so is there any hope for the future? Business is primarily about money, but what if the balance between technical improvements and a beautiful look is not maintained. "Emergency 2015" - the limit after which you need to make drastic changes in the technical component. Carte blanche from business and a rough idea of where to start the transformation. Why did you choose to go through refactoring? Why did you decide to split the monolith into microservices in 2015, when the hype was just emerging, instead of SOA and monolith? How did you choose where to start? How AWS S3 defeated Ceph and helped save the nerves and funds of DevOps? What nodes of the system have provided us with the opportunity to grow 10-15 times in 5 years without spending much more money on vertical scaling? Stable 1.5 billion letters in 2020.

The talk focuses on developing and integrating automation tools to enhance Supply Chain security. It addresses reproducible security practices with tools like Renovate and Wiz, as well as GitLab and JFrog Artifactory, to enforce consistent security scans seamlessly within existing workflows. We will cover centralized artifact management for improved oversight and consistency. Furthermore, we will discuss the seamless integration of security scans into deployment tooling, featuring automatic deployment blocks for vulnerabilities and a controlled override option for flexibility. The talk also examines tactics to keep the source code secure and up to date. We will explore the integration of runtime monitoring systems with detection capabilities and SLAs to manage and resolve issues on time.

Kubernetes Controllers and Operators are a trending topic in conferences, interviews, and production today. I will share the story of the evolution of our Promotion (Release) system, from simple Kubernetes API REST calls to Informers and Controllers, based on my own experience. This story is particularly interesting because it serves as a great case for personal growth for you as well as for your DevOps/SRE team. It touches on Kubernetes architecture details, Networking, GitOps, IaC, Caching, development patterns, and Golang data structures. Even if you have no development experience (as is the case for most of our team), I will share how a Cursor AI assistant became yet another — though virtual — engineer on our team. Bonus: 10 years of Kubernetes & trends KubeCon24 North America.

For the past three years, I have worked at LetsEnhance/Claid, an AI startup that enhances image quality and creates new backgrounds for customer products. While the infrastructure is always the same, it varies: large models, significant latency, and unreliable autoscaling. In this speech, I will discuss our perspective on AI infrastructure and our ideas for its improvement. The topic is for mid to senior-level engineers who are either already in AI or interested in understanding how it differs from traditional infrastructure.

I'll discuss how we solved the accumulated problems and what we got from it. Finally, we'll discuss what could have been done differently from the very beginning and how to search for that elusive balance in general.

This talk will address the issue of choosing between global hyperscalers like AWS and local cloud solutions for businesses and developers in Ukraine. We will consider what to do if resources are limited or AWS cloud services become too expensive due to unpredictable fees. We will discuss the pros and cons of building your own cloud, the risks of this solution, and how to ensure its reliable support. The presentation will focus on Ukrainian cloud solutions: from classic IaaS services to modern Kubernetes-based solutions for developers and specialized platforms for AI/ML projects. We will also consider how such solutions are priced and what approaches to user support are the most effective. This presentation will help businesses and developers find the best way to use cloud technologies in the Ukrainian context.
