This document discusses strategies for scaling mature systems. It identifies common scalability blockers like distributed transactions, resource contention, state/session management, and deployment processes. For distributed transactions, it explains the differences between ACID and BASE principles and strategies for implementing failure detection and handling. For resource contention, it recommends decoupling dependencies through asynchronous processes like caching. For state management, it suggests moving to stateless applications using an external session manager like Cassandra. And for deployment processes, it advises making applications stateless, configurable templates to allow elastic scaling through quick VM provisioning. The document is based on the experiences scaling an existing 10+ year old product at OpenJaw Technologies.
The document is a presentation by Mike Kavis on deriving value from enterprise DevOps. It discusses how DevOps aims to build better quality software faster and more reliably through collaboration between development and operations teams.

Enterprise DevOps in the Age of Docker & MicroservicesXebiaLabs
Tim Buntel & Sunil Mavadia discuss the following in this one-hour webinar:
What containers and microservices mean for existing software delivery processes.
Important considerations for successful adoption of containers and microservice architectures as part of the enterprise release pipeline.
How to ensure that security, compliance and governance standards are maintained when you finally do introduce them.
Application architectures have become more distributed, heterogeneous, and reliant on supporting infrastructure tiers. In 2018, we are seeing customers beginning to realize they need to expand their application performance monitoring (APM) capabilities to provide visibility of these supporting IT infrastructure components.
Application managers and IT teams are realizing that they need contextual visibility into how an infrastructure problem affects application performance, and seek APM solutions that can cross-correlate code-level and transaction-level performance with the health of the supporting physical, virtual, container and cloud infrastructures.
Watch this on-demand webinar and learn why this cross-correlation is so important and what's required to achieve it:
• Why monitoring applications in isolation will not be enough to monitor digital business service performance
• What's required for the enterprise to achieve total performance visibility
• How you can build an incremental plan for achieving transparency in digital service performance monitoring
Hybrid Cloud Transformation Fast Track.pptxzhunli4
This document discusses hybrid cloud and provides key considerations for a successful hybrid cloud deployment.

Get Loose! Microservices and Loosely Coupled Architectures DevOps.com
The recently published results from the 2017 State of DevOps Survey shows that loosely coupled architectures and teams are the strongest predictor of continuous delivery. Microservices and Containers are a great choice for creating these loosely coupled systems. But, many teams find it hard to decompose monolithic applications into Microservices, and they find it harder still to coordinate deployments and releases into the emergent “hyper-hybrid” operating environments.

The document discusses how Oracle Application Express (APEX) is the fastest route to developing applications in the cloud. It was designed for cloud computing with a simple architecture that allows easy deployment on Oracle's cloud infrastructure or on-premise. APEX requires only a browser to build powerful data-driven web apps using SQL and PL/SQL. It has a proven track record of being used by thousands of customers for cloud apps since 2002. The document argues that APEX's low-code development, portability across environments, and leveraging of Oracle databases and cloud services makes it ideal for cloud development.
Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Climate Impact of Software Testing at Nordic Testing DaysKari 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.

Cosa hanno in comune un mattoncino Lego e la backdoor XZ?Speck&Tech
ABSTRACT: A prima vista, un mattoncino Lego e la backdoor XZ potrebbero avere in comune il fatto di essere entrambi blocchi di costruzione, o dipendenze di progetti creativi e software. La realtà è che un mattoncino Lego e il caso della backdoor XZ hanno molto di più di tutto ciò in comune.

I am going to talk to you about software architecture and scalability.Most talks that I have attended, blogs or books that I have read on this subject make the same assumption:- You are developing a new system.- You don’t need to migrate existing functionality.- You have unlimited engineering resources.- This is typical for large corporates or academia.As software architects we have to deal with large mature systems, and it is obviously very expensive to rewrite these from scratch.The same holds for refactoring or migrating functionality to a new platform.As an architect, you may be given a lot of stick due to scalability issues with your system.So why don’t our systems scale?
The most common reason is that the environment that your software runs in has changed.This can be due to many factors. The most obvious are: - The number of users or traffic has increased. - The number of products you are offering has increased.But also, you may have a case where the purpose of a software component has changed over time.Your marketing or sales department may have decided that your internal test tool is something they can sell.This has actually happened in every single job that I have had since college - the worst case being the first tool that I ever wrote (phone call scanner to be used as evidence in court cases).All these environment changes put new demands on your software platform.Today I will talk about how we can make our existing systems scalable.
Focus for today will be on scalability.I will go through my interpretation of scalability, so that we share a common understanding of the term.
Performance is a single point on this graph.Scalability is the shape of the graph.In this case we see a system that scales linearly, the resource requirements increase linearly with the load on the system.This doesn’t necessarily mean that the performance in terms of response times, etc. remains constant.This graph shows a system that isn’t scalable.Performance is better than our first system (green), but at a certain point the resource requirements skyrocket.This is the ideal scenario, where a system scales better than linear.
Over the next 30 minutes I will take you through these common scalability blockers.There are quick wins in all of these areas, and I hope that what I present to you will help you make your system scale.
Unless you want to argue about old vs. new Pink Floyd, ACID (Syd Barret) is bad and BASE (Roger Waters) is good.ACID principle:Data consistency is the highest priorityAvailability is less importantPessimistic approachComplex and large overheadBASE principle:Consistency is less importantAvailability is the highest priorityOptimistic approachSimple and fastApproach:Assume that data will be eventually consistent, ORBuild processes to handle consistency exceptions
Latency – Overhead of coordinationPerformance – Sequential sequencing of operationsScalability – large resource requirements for single operationAvailability – operation fails if a single system failsAllowing your system to “fail” according to the traditional ACID methodology may actually make business sense. Do you really need your transactions to run as a single atomic operation?
OpenJaw’s Internet Booking Engine manages 2-phase transactions across multiple external systems.Most of these external systems are outside of our control, and include travel suppliers like - Expedia, HotelBeds, GTA - Amadeus, Sabre, SITA - Avis/Hertz - Payment gateways - Confirmation e-mailCheckout of a single shopping cart requires interaction with all of these systems, but from the consumer’s perspective this is a single booking with a single payment.We have the capability of running these as a 2-phase transaction, where payment and booking is done as a single all-or-nothing process. This makes all bookings slower than what they have to be, due to sequential processing.In most cases all systems return with a positive response – maybe with the exception of payment where there may be a relatively high failure rate due to the consumer’s credit limit. So why would we want a process that is consistently slow in order to cater for the 2-3% of requests where there are errors?A better approach is to charge payment first, and then run all bookings in parallel. Then we build processes around failed bookings, which could include alerting a call center agent to ring back the customer and propose an alternative product.
This is a summary of the changes we made to our transaction process.
You will have contention around internal and external resources.
It is very easy to build and integrate a cache.There is a range of potential platforms, and you must choose the one that suits your needs.In-memory databases like Redis offers extreme performance, but have limitations like size and failover.Distributed caches like Cassandra offer high scalability and failover, but do not perform as well as in-memory databases.SQL databases offer security in case the cached data is sensitive.Implementing basic caching done in three steps: - Build the cache key - Cache lookup - Cache storage
A cache is a simple way of buying performance by sacrificing data freshness or quality.In order to effectively cache you must measure both how well your cache performs (hit/miss rate) but also how good the data quality is. The latter is very often missed or ignored.You may also need to measure these for various product types and variations. In our case we measure per product type, and route (for flights) or destination (for hotels).This allows us to properly tune the cache – and achieving the ideal balance between performance and data-quality.
This is the theory!How do you do this in practice?In our case we had a stateless middleware platform that scaled linearly.The stateful front-end used standard J2EE session management, and became a barrier for scalability.J2EE sessions were accessed by our MVC platform, Java beans and JSPs.Changing how we managed sessions would mean a huge refactoring task, which would cost us months of engineering effort,
There are two ways of attacking this problem: - You can renew or replace your platform, which means you will have to refactor your application - You can change how your existing platform manages sessions.Our front-end application conformed to the J2EE spec, which allowed us to move to Tomcat. Tomcat is open-source and allows custom session managers to be implemented.On any platform where session/state is accessed through a single interface, you have the possibility of changing how session/state is persisted and shared.
Our custom Tomcat session manager uses Cassandra to store session data. This is a common approach in the PHP/LAMP world.Cassandra is the master for session data, and session data sits in the Tomcat session manager only for the duration of a single request.The session manager contains an in-memory cache (write-back or write-through) that exists for the lifetime of a single request.Allows use of a stateless (non-sticky) load balancer.Available as open-source: Google “tomcat Cassandra”
These are considerations for any distributed session/state management!Session object serialization must perform well: - Ensure that you only serialize what you need. - Optimize serialization, for instance by serializing XML using Xerces/XalanSession objects cannot be synchronized using Java locking. You may have to rewrite some session objects to be inherently thread-safe.You may also have to build code to handle inconsistencies between concurrent Ajax requests.One common pitfall when creating scalable systems is assuming that the network is always available. With this session manager, network bandwidth may become an issue! Consider using 3 network segments: - One in front-of your application - One for the middle-tier or back-end - One for Tomcat-CassandraWe implemented tunable compression in the Tomcat session manager: Trade-off between CPU and network bandwidth.
Making this happen isn’t that difficult!
Your application should be just that – an application.All data must be extracted to external stores: - Most applications store product data in back-end systems/databases. - You should store your session state in external storage. - You should also store all your configuration in external storage.Use a single URI or environment variable to point to your configuration store. Your hypervisor will allow you to set this variable per application node.The configuration store then points your application to the appropriate back-end and session store.This allows a single VM image to be used across all your environments; live, pre-live, UAT, test, etc.
