Strangeloop president Joshua Bixby walks through case studies of Strangeloop customers like AutoAnything.com and Artbeads.com to show how mortal companies have improved performance and achieved measurable success, including:
· Increased revenue by 13%
· Increased cart size by 6%
· Increased conversions by 9%
Joshua offers practical tips for successfully evangelizing performance within your organization. He also gives a snapshot of the current performance landscape in North America, as well as a sense of where the industry is headed.
An overview of web performance automation in the Production environment - "faster ways to make your website faster". Covers things like sample .htaccess files through to performance accelerators like mod_pagespeed and Aptimize through to DSA's like Cotendo.

Scale Your Application while Improving Performance and Lowering Costs (SVC203...Amazon Web Services
Scaling your application as you grow should not mean slow to load and expensive to run. Learn how you can use different AWS building blocks such as Amazon ElastiCache and Amazon CloudFront to “cache everything possible” and increase the performance of your application by caching your frequently-accessed content. This means caching at different layers of the stack: from HTML pages to long-running database queries and search results, from static media content to application objects. And how can caching more actually cost less? Attend this session to find out!

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.

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.

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.
