Building clouds with apache cloudstack apache roadshow 2018ShapeBlue
Talk given at Apache Roadshow, FOSS Backstage, Berlin, June 2018
Apache CloudStack is open source software designed to deploy and manage large networks of virtual machines, as a highly available, highly scalable Infrastructure as a Service (IaaS) cloud computing platform. This talk will give an introduction to the technology, its history and its architecture. It will look common use-cases (and some real production deployments) that are seen across both public and private cloud infrastructures and where CloudStack can be completed by other open source technologies.
The talk will also compare and contrast Apache Cloudstack with other IaaS platforms and why he thinks that the technology, combined with the Apache governance model will see CloudStack become the de-facto open source cloud platform. He will run a live demo of the software and talk about ways that people can get involved in the Apache CloudStack project.

Melbourne Chef Meetup: Automating Azure Compliance with InSpecMatt Ray
June 26, 2017 presentation. With the move to infrastructure as code and continuous integration/continuous delivery pipelines, it looked like releases would become more frequent and less problematic. Then the auditors showed up and made everyone stop what they were doing. How could this have been prevented? What if the audits were part of the process instead of a roadblock? What sort of visibility do we have into the state of our Azure infrastructure compliance? This talk will provide an overview of Chef's open-source InSpec project (https://inspec.io) and how you can build "Compliance as Code" into your Azure-based infrastructure.

Tradycyjne podejście do modelu sieci i zarządzania nią w wielu obszarach przechodzi do przeszłośći. Na PLNOG18 Piotr Wojciechowski pokazywał, jak przejść z modelu myślenia o konfiguracji sieci na programowanie na przykładzie REST API. Tym razem pokaże inną gałąź tej ewolucji jaką jest sieć w chmurze publicznej i hybrydowej na przykładzie AWS i Azure, opowiedzieć o różnicach między implementacjami sieci w chmurze publicznej, a tradycyjnych sieciach czy chmurze prywatnej, modelach migracji i tworzenia sieci w rozwiązaniach hybrydowych. Wszystko ze wskazówkami jak zabrać się za migrację i naukę.
An overview of multiple public, private, hybrid cloud options, including Amazon Web Services (AWS), Google Compute, Vmware vCloud Air, Azure, as well as CSP/MSP based private clouds. We take common use-cases, such as disaster recovery and compare each option. We'll also talk about network fabrics, direct network connectivity, ownership, management, compliance, and accountability.
In 2008, Harald van Breederode and Joel Goodman wrote a white paper titled "Performing an Oracle DBA 1.0 to Oracle DBA 2.0 Upgrade" in which they suggested DBAs needed to add storage and OS skills to remain relevant in a shifting technical landscape. The role of today's DBA has broadened considerably and with that comes a new set of abilities and concepts to be learned and mastered.
DBA 2.0 was written prior to the release of Oracle 11g and 12c, so the Oracle DBA 3.0 upgrade adds Cloud and virtualization to the DBAs repertoire. Their inclusion also demands that DBAs be able to better manage security and compliance challenges that come with hybrid and Cloud environments, the ability to adapt to continuous deployment cycles, and heterogenous and comingled data stores.
Most significantly DBA 3.0 signals an emergence of the DBA from a mostly utilitarian and anonymous role to one that is more in the limelight. The growing emphasis and influence of data and data-driven decision making means that the DBA must be a partner and driving force in the business and not simply a custodian of the data.
Learn what it will take to build or upgrade your skill set to Oracle DBA 3.0, and how to encourage and mentor a new generation of data professionals into the field.

Can Your Mobile Infrastructure Survive 1 Million Concurrent Users?TechWell
When you’re building the next killer mobile app, how can you ensure that your app is both stable and capable of near-instant data updates? The answer: Build a backend! Siva Katir says that there’s much more to building a backend than standing up a SQL server in your datacenter and calling it a day. Since different types of apps demand different backend services, how do you know what sort of backend you need? And, more importantly, how can you ensure that your backend scales so you can survive an explosion of users when you are featured in the app store? Siva discusses the common scenarios facing mobile app developers looking to expand beyond just the device. He’ll share best practices learned while building the PlayFab and other companies’ backends. Join Siva to learn how you can ensure that your app can scale safely and affordably into the millions of concurrent users and across multiple platforms.

Cloud Migration Paths: Kubernetes, IaaS, or DBaaSEDB
Moving to the cloud is hard, and moving Postgres databases to the cloud is even harder. Public cloud or private cloud? Infrastructure as a Service (IaaS), or Platform as a Service (PaaS)? Kubernetes for the application, or for the database and the application? This talk will juxtapose self-managed Kubernetes and container-based database solutions, Postgres deployments on IaaS, and Postgres DBaaS solutions of which EDB’s DBaaS BigAnimal is the latest example.
If you are considering a lift-and-shift from on-prem to public cloud, this talk is for you. Our team runs a centralized build farm for Nokia's software division. The build farm consists of a fleet of Jenkins Masters, a Kubernetes cluster, artifact storage, and various back-office services for monitoring and automation. This talk gives an overview of how we migrated our build farm from an on-prem OpenStack-based datacenter to AWS. It was a successful migration, but we made several mistakes along the way and would like to share what we learned.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan 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.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
17. Challenges
• C* does not have Auto Id generation.
• How to connect to C* with C#?
• Finding a connector with good Failure Tolerance.
• How to integrate our reporting system?
External API is locked to 64-bit integer (no strings).Increasing over time helps SQL Server indexingNo Identity column in C*TimeUUIDs – now and everything in the future
Solutions:SQL – table(s) with a single IDENTITY column; not infinitelyscalablePre-generated range – Matt Dennis, DataStax; ordering not guaranteed either.Instagram - http://instagram-engineering.tumblr.com/post/10853187575/sharding-ids-at-instagram; slick but we found it too late.
https://github.com/twitter/snowflakeRequirements: unique, time sortable, increasing, 64-bit int, fast, distributedTwitter already using itJava – yes, MS shop, but we can handle itThrift – maybe not ideal, but it’s familiarZookeeper is a drawback – but only needed for SF startup.
Still need to connect from our .NET app – rolled our ownThrift part is generated code Web app connects to local SF instance to save network hopCan failover to SF on other web nodes.Auto failover and recoveryhttp://timross.wordpress.com/2008/02/17/implementing-the-circuit-breaker-pattern-in-c-part-2/
Thrift is fine, but it would be too much to overcome in terms of its low levelness with our engineers.CQL is the future; easier for us to understand anywayDon’t know what we’re doing – need supportWould like the familiar feelCQL eliminated most players. FluentCassandra had everything else. DataStax not in the game yet.
Open source – we were able to contribute bug fixes; relatively activeNick very knowledgeable & responsiveIt was drop in and go for development – but that’s when we started stumbling a bit.
It was drop in and go for development – but that’s when we started stumbling a bit.Resources – taking too long; distracting leads; back to drawing board.
Really, the challenges is connecting WITH failure tolerance.
Along the way, learned about Hector.Wanted to know more about its features re: FluentCassandra, so reasearchedVariety of use cases including high transactionMuch better advanced feature set.Java – we’re not scared of it, but also not willing to rewrite entire business app.
(Transition to Reporting)
Migration Schema changes A lot of data Keep it in sync (dual threads)Get into production early – dual threaded requests, worked out really well, but…Data Import = Reality – we didn’t have a complete set of data imported. It turns out that our dataset size once imported dramatically effected performance, particularly in regards to how bloom filters and the JVM work with Cassandra. Break down communication barriers – C* DojoDeveloping against C* is a paradigm shift. It takes time for developers – start them early.Understanding your IO profile is really important – This is the essence of noSQL, start here. Cassandra is best at writing Most data systems, write once – read many We’re actually a read-heavy workload.
Sizing and hardware - This is why the above points are so important – increase your chances of getting it right the first time - You might get it wrong – we did – so set those expectations up front - Commodity means readily available and high value.. Doesn’t have to be ‘consumer’ grade. - Leverage cloud resources in working toward right sizing your cluster Cassandra changes quickly, you need to keep up – It’s open source and immature compared to SQL Server, MySQL, Oracle – For example, object level security was just implemented in the last version of C*Scalable systems like C* have a massive amount of knobs, you need to know them – There are hundreds, you need to expect to have someone focused on this.
