This document discusses leading a transformation to cloud technologies. It provides guidance in 4 key areas: 1) Investing to drive a high rate of change, 2) Picking big projects to replatform early, 3) Having a point of view on being cloud native, and 4) Preparing to be in a hybrid state for some time. The goal is to transition to the cloud in a way that is faster, better, cheaper, safer, and more reliable. Cloud services provide many building blocks to evolve architectures, but transformations take time and hybrid states are common during the process.

Five Rules

Subbu Allamaraju

On March 12, 2019 Google experienced a 4 hour and 10 minute service disruption in their internal blob storage service. The outage was caused by a configuration change made by SREs on March 12th to reduce storage usage, which had the unintended side effect of overloading a key system. The document discusses principles for building highly available systems drawn from Google's experiences, including embracing constant change, hybrid architectures, observability, and value-based decision making.

Taming the Rate of Change

Subbu Allamaraju

How to bring in safety back into an organizational culture when the contemporary patterns used to increase the rate of change also contribute to increased fragility? In this talk, we will look at contributing factors, the limits of chaos testing, and patterns and practices needed to support a high rate of change while also maintaining system safety. Presented at: Feb 6, 2019 at https://conferences.oreilly.com/software-architecture/sa-ny/schedule/2019-02-06 Mar 26, 2019 at https://t3ch.amadeus.com/agenda

Subbu Allamaraju

This document discusses Netflix's transition to a cloud native architecture and lessons learned that may be applicable to other companies. The key points are: 1. Organic migrations don't work and big changes need to be planned from the start. 2. Embracing managed cloud services and standardizing what to centralize makes migrations easier. 3. Security, controls, and costs need consideration upfront to avoid issues later. 4. Having guardrails for decision making is important but not being too constrained. 5. Learning from failures and getting comfortable with change is part of becoming cloud native.

Turning Containers into Cattle

Subbu Allamaraju

The document discusses how treating containers as "cattle" rather than "pets" can help address issues like heterogeneity, operational overhead, and change fragility in container management. It advocates implementing the classical automation cycle of provisioning, deploying, monitoring, and remediating containers while observing their current state and converging it to the desired state as described in policies. This treats containers as generic and ephemeral resources rather than individually managed assets, hiding the full infrastructure stack behind the cluster manager.

Engineering operations

Subbu Allamaraju

The document describes the evolution of engineering operations at eBay from a small manually maintained dev/test cloud to a large automated production infrastructure running the business. It went from a dev to ops ratio of 1:0 with no automation and thousands of nodes distributed across several availability zones operated 24x7 with a dev to ops ratio of 5:1. The document recommends treating infrastructure as code, managing drift through automation and audits, measuring everything as another product feature, and fostering a culture of shared accountability between dev and ops.

Open stack@ebay

Subbu Allamaraju

- eBay runs OpenStack as its private cloud infrastructure, providing on-demand access to computing resources for various eBay brands and services on shared infrastructure. - eBay uses OpenStack APIs and multiple availability zones and regions to provide high availability and scale capacity across its global infrastructure. - eBay has developed tools like StackWatch and StackMetrics to monitor OpenStack performance, simulate workloads, and detect issues in the cloud.

Making Things Work Together

Subbu Allamaraju

The document discusses building an interoperable programmable web through common agreements on discovery, linking, schemas, media types, formats and interfaces. It proposes using HTTP as the common protocol and representing data through common formats to allow different systems and APIs to interact. It also suggests using SQL-like constructs to enable operations like querying, filtering, joining and orchestrating requests across multiple APIs.

ql.io at NodePDX

Subbu Allamaraju

This document discusses the ql.io open source project, which provides a domain specific language (DSL) for making HTTP requests. The DSL allows HTTP resources to be treated like database tables, enabling CRUD operations on those resources with a SQL-like syntax. Ql.io can be used as an HTTP gateway and allows parallelizing and joining requests. It aims to simplify writing code for making API calls. The document provides examples of using the ql.io DSL and discusses how it can be used as a Node.js module.

ql.io: Consuming HTTP at Scale

Subbu Allamaraju

This document summarizes ql.io, a domain specific language for consuming HTTP APIs. Ql.io allows API calls to be made with fewer lines of code and reduced data sizes compared to traditional HTTP requests. It handles parallelizing requests and joining responses implicitly. Ql.io also allows mapping HTTP resources to SQL-like queries, enabling sequential and parallel queries over multiple APIs with a simple syntax. It can be used as an HTTP gateway or from Node.js.

Measuring REST

Subbu Allamaraju

This document discusses measuring the effectiveness of REST architectures. It outlines different levels of understanding REST and lists qualities that could be measured like performance, scalability, simplicity and constraints adherence. However, the document argues that proving REST leads to these qualities is difficult without tying the constraints to specific scenarios and priorities. It proposes a process to agree on what qualities matter, contextualize them into measurable scenarios, prioritize scenarios, and then evaluate solutions based on how well they meet the prioritized scenarios.

REST: Theory vs Practice

Subbu Allamaraju

This document discusses REST theory versus practice. It begins with introducing the two speakers, Subbu Allamaraju and Mike Amundsen. The objectives of the talk are then outlined, which are to understand that REST is a set of constraints that can be knowingly relaxed, work with underlying protocols, and apply sound software engineering. Common REST principles are then explained including identifying resources, using URIs, designing representations, using a uniform interface, and using hypermedia as the engine of application state. An example address book REST API is then demonstrated. The talk concludes by discussing practical considerations when implementing REST including managing concurrency, being creative with URIs, and that IDs alone are not as good as full URIs.

RESTful Web Apps - Facts vs Fiction

Subbu Allamaraju

Pragmatic Rest

Subbu Allamaraju

This document summarizes Subbu Allamaraju's presentation on building RESTful web APIs. The presentation covers REST architecture constraints including identifying resources with URIs, manipulating resources through representations, self-descriptive messages, and hypermedia as the engine of application state. It also discusses building RESTful HTTP APIs by using the HTTP methods like GET, POST, PUT, DELETE according to their definitions and designing resources around domain nouns. The presentation provides examples of RESTful and non-RESTful API designs.

Climate Impact of Software Testing at Nordic Testing Days

Kari Kakkonen

My slides at Nordic Testing Days 6.6.2024 Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Epistemic Interaction - tuning interfaces to provide information for AI support

Alan Dix

Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024 https://alandix.com/academic/papers/synergy2024-epistemic/ As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

In the rapidly evolving landscape of technologies, XML continues to play a vital role in structuring, storing, and transporting data across diverse systems. The recent advancements in artificial intelligence (AI) present new methodologies for enhancing XML development workflows, introducing efficiency, automation, and intelligent capabilities. This presentation will outline the scope and perspective of utilizing AI in XML development. The potential benefits and the possible pitfalls will be highlighted, providing a balanced view of the subject. We will explore the capabilities of AI in understanding XML markup languages and autonomously creating structured XML content. Additionally, we will examine the capacity of AI to enrich plain text with appropriate XML markup. Practical examples and methodological guidelines will be provided to elucidate how AI can be effectively prompted to interpret and generate accurate XML markup. Further emphasis will be placed on the role of AI in developing XSLT, or schemas such as XSD and Schematron. We will address the techniques and strategies adopted to create prompts for generating code, explaining code, or refactoring the code, and the results achieved. The discussion will extend to how AI can be used to transform XML content. In particular, the focus will be on the use of AI XPath extension functions in XSLT, Schematron, Schematron Quick Fixes, or for XML content refactoring. The presentation aims to deliver a comprehensive overview of AI usage in XML development, providing attendees with the necessary knowledge to make informed decisions. Whether you’re at the early stages of adopting AI or considering integrating it in advanced XML development, this presentation will cover all levels of expertise. By highlighting the potential advantages and challenges of integrating AI with XML development tools and languages, the presentation seeks to inspire thoughtful conversation around the future of XML development. We’ll not only delve into the technical aspects of AI-powered XML development but also discuss practical implications and possible future directions.
