RabbitMQ is used in several example applications and real case studies. Three example codes demonstrate: 1) the RabbitMQ tutorial using request/reply queues, 2) RPC using correlated messages, and 3) Celery's distributed task queue using polling. Case studies show RabbitMQ for: 1) message passing between Zenoss daemons, 2) Nova controller RPC, 3) Instagram's task queue with Celery, 4) MercadoLibre's service bus architecture, and 5) Indeed.com's distributed crawling. RabbitMQ provides reliability, scalability, and asynchronous messaging between distributed applications and microservices.

INF107 - Integrating HCL Domino and Microsoft 365Dylan Redfield
Is your organization flirting with a move to Microsoft 365? Or are you managing an infrastructure that includes both Domino servers and Microsoft 365 cloud services? As Microsoft 365’s footprint grows, many HCL Domino environments are finding the need for the two technologies to coexist. This session will discuss best practices, native options and third-party tools to allow the two environments to work together, ultimately reducing your overhead and allowing your users to be productive. Just because you are running dual environments, does not mean you have to duplicate efforts to manage them. Let us give you tips on how to save time and give your users a cohesive experience.

Resilient Kafka: How DNS Traffic Management and Client Wrappers Ensure Availa...VanessaVuibert1
Kafka clients sometimes have problems producing messages because of an incident or maintenance. In most cases these issues are short lived, but clients get paged and while long incidents are rare, they are memorable. In this talk, we'll run through our Kafka infrastructure at Shopify and how clients connect to it. Next, we'll describe our solution for performing failovers using DNS. Afterwards, we'll look at some real world scenarios where this system saved us from major outages. In conclusion, Kafka clusters are more resilient to infrastructure hiccups with a DNS traffic manager and opinionated client wrappers.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.

The Art of the Pitch: WordPress Relationships and SalesLaura Byrne
Clients don’t know what they don’t know. What web solutions are right for them? How does WordPress come into the picture? How do you make sure you understand scope and timeline? What do you do if sometime changes?
All these questions and more will be explored as we talk about matching clients’ needs with what your agency offers without pulling teeth or pulling your hair out. Practical tips, and strategies for successful relationship building that leads to closing the deal.
Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

– AMQP transaction – deliver ACK to sender after
message received
– AMQP distributed transaction – deliver ACK to a
3rd party software after message received
– Access – a realm based access control model
we think these are irrelevant to ADDM

• message-id
• reply-to

• Each RPC call has its own unique message-id generated by UUID library
22. Case 3: Instagram
• Web server uses nginx
• Messaging system use
RabbitMQ
– Scalability: self-made message
broker, dispatch message in RR
– Reliability: RabbitMQ cluster
• Worker system use Celery
– Celery is distributed task queue
– worker concurrency model
• slow task: pre-fork pool
• fast task: gevent
• Overall throughput
– 25k application threads

– 4K tasks per second
– Also monitor queue length
