Agenda, slides and recording: https://indico.egi.eu/event/5711/
About: Rucio is a data management software, originally developed for ATLAS at CERN to supersede their previous data management software 10 years ago. Since then Rucio has been constantly developed by ATLAS and other communities that have come to use Rucio, ensuring that it is a feature rich, and well maintained open software.
Multi-VO Rucio implemented by the STFC in the UK hosts Rucio as a service for many communities. This is to provide communities the opportunity to use Rucio for their data management solution, without having to learn about, and host their own instance of Rucio.
FTS is a low level data movement service, responsible for reliable bulk transfer of files between storages. It's responsible for globally distributing the majority of the LHC data across the WLCG infrastructure and it supports many communities is EGI.
In this webinar we introduce the main functionalities and show how to interact with the services in order to schedule transfers.

|Target Audience: Scientific communities, developers, IT service providers, and end users.||"Using Dynamic DNS service in the EGI Cloud infrastructure" (June, 2021)|
Agenda, slides and recording: https://indico.egi.eu/event/5559/
About: Nowadays, more and more services are dynamically deployed in Cloud environments. Usually, the services hosted on virtual machines in Cloud are accessible only via IP addresses or pre-configured hostnames given by the target Cloud providers, making it difficult to provide them with meaningful domain names.
The Dynamic DNS service provides a unified, federation-wide Dynamic DNS support for VMs in EGI infrastructure. Users can register their chosen meaningful and memorable DNS host names in given domains (e.g. my-server.vo.fedcloud.eu) and assign to public IPs of their servers. By using Dynamic DNS, users can host services in EGI Cloud with their meaningful service names, can freely move VMs from sites to sites without modifying server/client configurations (federated approach), and can request valid server certificates in advance (critical for security).
The webinar will provide demonstration and tutorial, also practical advice on using Dynamic DNS service in realistic user scenarios.

|Target Audience: Site administrators and cluster administrators; CVMFS power users.||"CernVM-FS for Containers" (October 2020)|
Agenda, slides and recording: https://indico.egi.eu/event/5251/
About: Delivering complex software stacks across a worldwide distributed system is a challenge in high-throughput scientific computing. The global-scale virtual file system CernVM-FS distributes more than a billion software binaries to hundreds of thousands of machines around the world.
In this webinar, we will present the latest developments with regard to CernVM-FS container integration. Containers and CernVM-FS team up nicely: containers provide the isolation capabilities that decouple the application stack from the underlying platform and CernVM-FS provides efficient distribution means for the containerized software binaries. Containers are an enabling technology to harness opportunistic resources and HPC facilities. CernVM-FS enables the use of such resources at scale. In this webinar, we will show how existing repositories can be used with several popular container runtimes, such as docker, podman, singularity, and kubernetes. We will also show how operating system containers themselves can be efficiently distributed through CernVM-FS. Lastly, we will highlight an upcoming new way of publishing content from within a container. This makes it easy to set up, build and test and deploy-to-cvmfs pipelines on kubernetes.

Agenda, slides and recording: https://indico.egi.eu/event/5089/
About: The EGI DataHub allows users to make their data available using different levels of access: from completely unrestricted open access to open data to authenticated access to closed data sets. This is possible as a result of the seamless integration with the EGI AAI service. The data hosted on the EGI DataHub can be readily accessible by cloud Virtual Machines (VMs) or running grid jobs thanks to full integration with EGI Federated Cloud and High-Throughput compute resources. The use of protocols such as POSIX and web services guarantees easy and scalable access to data from cloud and HTC applications. This ensures maximum compatibility with existing applications and minimum hassle for developers and users alike. The EGI DataHub is built on top of the EGI Open Data Platform using Onedata technology to connect a wide range of existing storage services, regardless of their underlying technology (e.g. Lustre, Amazon S3, Ceph, NFS, or dCache).
During this webinar the QoS and hybrid cloud data processing scenarios for distributed EOSC environments based on EGI DataHub and Onedata solutions will be introduced.
|Target Audience: Scientific communities and IT-service providers who operate IdP for them.||"The EGI AAI Check-In service for scientific communities" (May 2020)|
Agenda, slides and recording: https://indico.egi.eu/event/5088/
About: The EGI Check-in service (also called EGI AAI proxy) enables access to EGI services and resources using federated authentication mechanisms. Specifically, the proxy service is operated as a central hub between federated Identity Providers (IdPs) residing ‘outside’ of the EGI ecosystem, and Service Providers (SPs) that are part of EGI. The main advantage of this design principle is that all entities need to establish and maintain technical and trust relation only to a single entity, the EGI AAI proxy, instead of managing many-to-many relationships. In this context, the proxy acts as a Service Provider towards the Identity Providers and as an Identity Provider towards the Service Providers.
Through the EGI AAI proxy, users are able to authenticate with the credentials provided by the IdP of their Home Organisation (e.g. via eduGAIN), as well as using social identity providers, or other selected external identity providers (support for eGOV IDs is also foreseen). To achieve this, the EGI AAI has built-in support for SAML, OpenID Connect and OAuth2 providers and already enables user logins through Facebook, Google, LinkedIn, and ORCID. In addition to serving as an authentication proxy, the EGI AAI provides a central Discovery Service (Where Are You From – WAYF) for users to select their preferred IdP.
The EGI AAI proxy is also responsible for aggregating user attributes originating from various authoritative sources (IdPs and attribute provider services) and delivering them to the connected EGI service providers in a harmonised and transparent way. Service Providers can use the received attributes for authorisation purposes, i.e. determining the resources the user has access to.
During this webinar we will give an overview about the service and provide guidelines to support the resource providers’ and communities' needs for federated access through the EGI AAI Check-In service. The webinar will also cover more advanced workflows for addressing non-web-based access use cases (e.g. command line and API).
