The document summarizes the changes that have occurred in system administration over time. It discusses how software delivery has shifted from CDs/DVDs to online and continuous delivery. Infrastructure deployment has evolved from manual installations to tools enabling reproducible deployments. Virtualization became common in the 2000s. Infrastructure as code principles including treating infrastructure configuration as code, versioning, and testing best practices are discussed. Monitoring has shifted from tools like BigBrother to Nagios and newer solutions. Emerging technologies like Docker, Packer, orchestration tools, and metrics/monitoring are also summarized.

The System Administrator Role in the Cloud Era: Better Than Ever (ENT212) | A...Amazon Web Services
With developers and business leaders driving the charge into cloud computing, where does this leave the IT department and, to put it bluntly, me, the sysadmin? Fear not, IT operation skills are highly relevant and in demand in the cloud era, but it might take a little repositioning on your part to get the opportunity. In this session, Forrester analyst James Staten shares how the leading sysadmins are engaging the business on their cloud journey and what they have done to evolve their role, advance their skills, and position themselves as IT change agents and leaders for the next generation.

All Things Open : Crash Course in Open Source Cloud Computing Mark Hinkle
Very few trends in IT have generated as much buzz as cloud computing. This session will cut through the hype and quickly clarify the ontology for cloud computing. The bulk of the conversation will focus on the open source software that can be used to build compute clouds (infrastructure-as-a-service) and the complimentary open source management tools that can be combined to automate the management of cloud computing environments.
The session will appeal to anyone who has a good grasp of traditional data center infrastructure but is struggling with the benefits and migration path to a cloud computing environment. Systems administrators and IT generalists will leave the discussion with a general overview of the options at their disposal to effectively build and manage their own cloud computing environments using free and open source software.

OSAC16: Unikernel-powered Transient Microservices: Changing the Face of Softw...Russell Pavlicek
In most current microservice-based architectures, the machine images powering the microservice are quite traditional: a full software stack from operating system to application, which takes significant resources to host and plenty of time to start and stop. As a result, most current microservice workloads are persistent, having to start before they are needed and sitting idle when there’s no work to do. This wastes precious resources and slows the application’s ability to scale out as workloads require.
The arrival of lightweight technologies like Docker and containers have opened the door to lighter workloads in the microservice arena, but the advent of unikernels might be a game changer. These ultralight, highly secure workloads combine the entire software stack—from operating system functions to application—into a single, tiny package that runs directly on a hypervisor. Start times for many unikernel-based VMs can be measured in milliseconds, raising the question: why waste time and resources with persistent microservices? Why not consider transient microservices, which appear when there is something to do and disappear immediately thereafter?
While the use of transient microservices could free up much computing power, it will also change the architecture and orchestration of software solutions. The concept of services that may have a lifetime measured in seconds—or less—does not currently exist in popular cloud-based systems.
OSDC 2015: Kris Buytaert | From ConfigManagementSucks to ConfigManagementLoveNETWAYS
In the beginning there was CFEngine, and the learning curve was high, then came Puppet , Chef and the learning curve was still high.
Now we have Ansible , for everyone that wasn't smart enough to learn the original tools. Or wasn't that the problem ?
For some people Infrastructure as Code became a goal alone, not caring about the infrastructure, Junior people wanted to learn Puppet, but forgot about the service they were configuring. Too Complex, Too much effort, .. And then containers came.
Taking Docker to Production: What You Need to Know and DecideBret Fisher
DevOps in the Real World is far from perfect, yet we all dream of that amazing auto-healing fully-automated CI/CD micro-service infrastructure that we'll have "someday." But until then, how can you really start using containers today, and what decisions do you need to make to get there? This session is designed for practitioners who are looking for ways to get started now with Docker and Swarm in production. This is not a Docker 101, but rather it's to help you be successful on your way to Dockerizing your production systems. Attendees will get tactics, example configs, real working infrastructure designs, and see the (sometimes messy) internals of Docker in production today.

Cobbler - Fast and reliable multi-OS provisioningRUDDER
In a lot of companies, machine deployment is a delicate subject: every administrator has his own recipe, using CD-ROMs, static binary images deployed via the network, peer delegation ...
However, one solution makes the consensus when it comes to automated mass deployments ( except in the Cloud ): PXE boot. The main cons are that the deployment and the management of such a service is a pain, and every OS has its own installation automation system.
This is where Cobbler saves the day: it enables a painless and reliably to create a PXE service, usable on either virtual or physical machines, while beeing the most agnostic possible towards the target OSes and its preconfiguration system (preseed, kickstart, sysprep, ...) while offering the possibility to handle lots of configuration parameters in a modular fashion (network, partitionning, user accounts, configuration management agent...)
This conference aims to introduce the audience to the general concepts of Cobbler, and some scenarios where it would be a useful solution.
Eager to learn more about OpenStack? This presentation provides an overview of OpenStack basics and an introduction to the types of storage in OpenStack. Choosing the right storage for your cloud can be the hardest part of building out your environment – this is a great primer to picking the right storage for your OpenStack deployment.
Containers: from development to production at DevNation 2015Jérôme Petazzoni
In Docker, applications are shipped using a lightweight format, managed with a high-level API, and run within software containers which abstract the host environment. Operating details like distributions, versions, and network setup no longer matter to the application developer.
Thanks to this abstraction level, we can use the same container across all steps of the life cycle of an application, from development to production. This eliminates problems stemming from discrepancies between those environments.
Even so, these environments will always have different requirements. If our quality assurance (QA) and production systems use different logging systems, how can we still ship the same container to both? How can we satisfy the backup and security requirements of our production stack without bloating our development stack?
In this sess, you will learn about the unique features in containers that allow you to cleanly decouple system administrator tasks from the core of your application. We’ll show you how this decoupling results in smaller, simpler containers, and gives you more flexibility when building, managing, and evolving your application stacks.
Most people will claim that this never happens, others hope it never happens, but it happened on March 10, 2021, and it was not just the 1 datacenter that got impacted, but the whole campus of the provider that got powered down. This talk will explain how our customers survived this outage, how our culture, opensource tooling and automation saved the da(y,ta). A talk about disaster recovery, business continuity plans and building cloud agnostic stacks that survive disasters.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

13. Physical to Virtual
WARNING : Adoption vs Introduction
●
Up till 2000 , Virtualization was a desktop
thing, running emulation on your desktop (Plex,
Bochs
●
Early 2000's Paravirtualization , Xen starts and
gains adoption
●
August 2006 : Amazon announced EC2
●
2009 : US started adopting EC2, Europe never
really did
●
2012 – now : Private clouds
14. Virtualization should be Cheap
●
1 host with way too much services
•
●
No isolation, dependency hell , management
hell
1 host multiple vm's , same CAPEX
•
VM's are cheap !
●
Public clouds => multiple vm's , growing OPEX
●
Private clouds => multiple vm's same CAPEX
15. What has changed
●
End users working 9-5
●
Local users using your application during
daytime
●
A global economy, no downtime an be
tolerated
16. High Availability & Scaleout
●
KISS
●
Clustered Storage is finally in it's 10's
●
Most apps still don't get it
•
Stateless vs Statefull
17. For years we've tolerated humans to to make
structural manual changes to the infrastructure
our critical applications are running on.
Whilst at the same time demanding those critical
applications to go trough rigid test scenarios.
Who let this happen ?
18. Infrastructure as Code
●
Treat configuration automation as code
●
Development best practices
•
Model your infrastructure
•
Version your cookbooks / manifests
•
Test your cookbooks/ manifests
•
Dev/ test /uat / prod for your infra
●
Model your infrastructure
●
A working service = automated ( Application Code +
Infrastructure Code + Security + Monitoring )
●
Think Puppet, Chef, Cfengine, ....
