Amazon Web Services

At Atlassian, we create popular software tools to help every team unleash their full potential. We use our issue tracking tool JIRA to handle customer support issues from around the globe. As the business grew, we decided to move from a single server instance of JIRA to our JIRA Data Center product on AWS infrastructure to increase reliability, scale, and security. JIRA Data Center's requirement to use a shared file system caused us to try several in-house and third-party solutions prior to the availability of Amazon Elastic File System (Amazon EFS). We chose EFS for its performance, ease of use, automatic scaling, and out-of-the-box distribution capabilities. In this session, we discuss how Atlassian uses EFS to run JIRA Data Center. Topics include the technical architecture, how and why we chose EFS, our recommendations, and the lessons learned along the way.

Amazon Web Services

At Spokeo, we are running a fast, big data, and high-traffic website providing people search services. But at our scale, we started to reach limitations to how fast our conventional web stack could do things and concluded that a Ruby on Rails–only solution simply couldn't keep up. In this session, we cover some of the options we had to solve this problem and why we chose Amazon Elastic File System (Amazon EFS) as a central part of our solution with metrics and benchmarking. Using EFS, we were able to take response times down from 250 ms to below 70 ms. We look into the architecture of the solution and lessons we learned along the way. In the end, we find that faster response times are just the beginning of the benefits that we see.

Epistemic Interaction - tuning interfaces to provide information for AI support

Alan 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.

"Impact of front-end architecture on development cost", Viktor Turskyi

Fwdays

I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

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. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle. Gopinath Rebala Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.

6. DR & HA • RTO: 24 hours. Aim for 2 hours. • RPO: 4 hours. Aim for 15 mins for future system. • HA: 99.5% ~ 5 nights down time per year. • Backup Retention: – 3 days for 4 hours snapshots. – 60 days for daily backups.

7. Current Architecture

8. Challenges • RTO of 2 hours, RPO of 15 mins. • No disk array on AWS  Have to deal with bit rot, disk failures. • Data growth 20% per year. • Choose Oracle RDS or Oracle on EC2? • Choose instance type that optimized for EBS.

9. First solution • What are the problems?

10. Our Solution • How is this solution better?

11. Cost Saving • Instance type for instances: r3.4xlarge – 10 Gbps – 18000 IOPS for free • Our solution: save 70% of AWS infrastructure cost.
