Assembly Language Tutorials for Windows - 04 Data Transfers Part-3

Sangram Kesari Ray

This document discusses jump and loop instructions in assembly language. It explains that JMP is an unconditional jump instruction that transfers execution to the specified destination. A JMP instruction can create an infinite loop by jumping back to its own location. LOOP is a loop instruction that decrements the ECX register and jumps back to the destination label if ECX is not zero, allowing code to repeat. The document provides a demo example using MOV to initialize ECX as the loop counter, and LOOP to repeat the block incrementing EAX until ECX reaches zero.

Messaging with amqp and rabbitmq

Selasie Hanson

The document envisions further serverless integration like rebuilding the admin interface and customer portal.

Different I/O Access Methods for Linux, What We Chose for ScyllaDB, and Why

ScyllaDB

When most server application developers think of I/O, they consider network I/O since most resources these days are accessed over the network: databases, object storage, and other microservices. However, the developer of a database must also consider file I/O. This webinar provides a detailed technical overview of the available choices for I/O access and their various tradeoffs. We then explain why ScyllaDB chose asynchronous direct I/O (AIO/DIO) as the access method for our high-performance low latency database and review how that decision has impacted our engineering efforts as well as our product performance. We will cover: - Four choices for accessing files on a Linux server: read/write, mmap, Direct I/O (DIO) read/write, and asynchronous direct I/O (AIO/DIO) - The tradeoffs among these choices with respect to core characteristics such as cache control, copying, MMU activity, and I/O scheduling - Why we chose AIO/DIO for ScyllaDB and a retrospective on that decision seven years later

How bol.com makes sense of its logs, using the Elastic technology stack.

Renzo Tomà

Bol.com uses the Elastic (ELK) stack to make sense of logs from over 1,600 servers and 500-600 million events per day. Key aspects of their system include: 1. Shipping JSON-formatted log events from sources like Apache, databases, and applications to Redis queues to allow multiple Logstash instances to process events in real-time without data loss. 2. Enriching log events with information like request IDs to correlate requests across services, and IP-to-role mappings to identify client roles. 3. Using Elasticsearch aggregations and transformations to generate a directed graph of service dependencies based on logs, to help understand their distributed architecture.

XMPP In Real Time

guest488a24

XMPP is a real-time messaging protocol that allows clients to exchange messages and presence information over XML streams. It provides a bidirectional communication channel that servers can use to push updates to clients, avoiding the need for polling. XMPP defines core semantics for establishing streams, authenticating users, and sending message and presence stanzas. These can be extended through XMPP Extension Proposals to support new use cases like voice calls, file sharing, and building web services that communicate in real-time. Popular applications of XMPP include instant messaging, chat applications, and Comet-style web APIs.

The Good, the Bad and the Ugly of Migrating Hundreds of Legacy Applications ...

Josef Adersberger

Running applications on Kubernetes can provide a lot of benefits: more dev speed, lower ops costs, and a higher elasticity & resiliency in production. Kubernetes is the place to be for cloud native apps. But what to do if you’ve no shiny new cloud native apps but a whole bunch of JEE legacy systems? No chance to leverage the advantages of Kubernetes? Yes you can! We’re facing the challenge of migrating hundreds of JEE legacy applications of a major German insurance company onto a Kubernetes cluster within one year. We're now close to the finish line and it worked pretty well so far. The talk will be about the lessons we've learned - the best practices and pitfalls we've discovered along our way. We'll provide our answers to life, the universe and a cloud native journey like: - What technical constraints of Kubernetes can be obstacles for applications and how to tackle these? - How to architect a landscape of hundreds of containerized applications with their surrounding infrastructure like DBs MQs and IAM and heavy requirements on security? - How to industrialize and govern the migration process? - How to leverage the possibilities of a cloud native platform like Kubernetes without challenging the tight timeline?

FreeSWITCH as a Microservice

Evan McGee

This document discusses microservices architecture compared to a monolithic architecture. A microservices architecture breaks an application into smaller, independent services that each perform discrete functions. This allows for more rapid development and improved scalability. However, a microservices architecture is also more complex to deploy and manage. The document provides an example of how a VoIP application could use a microservices approach by breaking components like billing, fraud detection, and call analytics into separate services. It also discusses using Docker containers and services to deploy and scale the microservices architecture.

Microservice Teams - How the cloud changes the way we work

Sven Peters

A lot of technical challenges and complexity come with building a cloud-native and distributed architecture. The way we develop backend software has fundamentally changed in the last ten years. Managing a microservices architecture demands a lot of us to ensure observability and operational resiliency. But did you also change the way you run your development teams? Sven will talk about Atlassian’s journey from a monolith to a multi-tenanted architecture and how it affected the way the engineering teams work. You will learn how we shifted to service ownership, moved to more autonomous teams (and its challenges), and established platform and enablement teams.
