Microservices Delivery Platform. Tips & Tricks

Andrey Trubitsyn

1. A microservices delivery platform consists of a microservices platform combined with CI/CD pipelines. It allows delivering microservices through continuous integration and continuous delivery. 2. Example platforms rely on open source technologies from Netflix and use dozens of ECS clusters and hundreds of microservices across Java, .NET, and Node.js. CI/CD pipelines are shared through templates. 3. Lessons learned include making CI and CD pipelines distinguishable, updating templates is difficult, and generators save effort but require ownership and version management. Naming, cost tracking, documentation, and dedicated testing are also important.

Software Architecture in the age of Cloud Computing

Jaroslav Gergic

The age of cloud computing presents the software architects with a unique set of opportunities as well as a unique set of challenges. Designing, building, and operating applications at cloud scale has changed the very nature of software architecture discipline to accommodate a much larger set of objectives and skills. Prior to the cloud era, software architecture was primarily about fulfilling functional requirements while maintaining code modularity and meeting a narrow set of non-functional requirements, such as performance. The cloud-era architect needs to accommodate not only functional requirements and customer-defined throughput and performance requirements, but also a large set of non-functional requirements related to cyber security, compliance, and most notably also the financial/cost characteristics, which at cloud scale can make or break a software-as-a-service company. The whole discipline of software architecture just became not only wider to accommodate all the above aspects, but also deeper as cloud-scale architecture spans all layers of software all the way down to operating system kernel tuning and in the case of private cloud also requires hardware know-how and hardware assembly design closely aligned with high-level application workload requirements to achieve reasonable performance and economics at cloud scale.

This document presents a proposed design for a product comparison tool on Dell's website. It includes three main sections for users to select options to narrow down suitable laptop models: Product Usage, Product Basics, and Additional Features. When users select criteria like price range and processor, unsuitable models would be grayed out. A reset option allows restarting the comparison. The results would display specifications for comparable models to aid selection. Additional help, SMB resources, and related products are also provided. The tool aims to simplify laptop selection through an interactive filtering and specification presentation process.

SIGRed - Monitoring and Detecting with Splunk

Anthony Reinke

Drew Church and Bryan Pluta of Splunk presented to the Nebraska Splunk User Group on August 13th, 2020 about SIGRed. The idea of this talk came from a blog post on July 17th on the Splunk site with a title of "Checking for SIGRed (CVE-2020-1350) and CISA ED 20-03 with Splunk (https://www.splunk.com/en_us/blog/security/checking-for-sigred-cve-2020-1350-and-cisa-eod-20-03-with-splunk.html?_lrsc=84746313-f6fe-401e-b552-47ba27adff3c). For those who haven’t heard about CVE-2020-1350, it is an unauthenticated, remote code execution (RCE) vulnerability in Microsoft Windows Domain Name System (DNS) servers. Successful exploitation allows attackers to run any code they want with local SYSTEM access. RCEs are bad vulnerabilities, unauthenticated ones are even worse. Pair this with one of the most common authentication platforms (Microsoft Active Directory), and you’re in for a world of hurt.

Binding android piece by piece

Bucharest Java User Group

This BJUG presentation is focused on the unique inter-process communication (IPC) mechanism introduced by Android, namely Binder. As such, we will be exploring the entire Android software stack, starting from the Linux kernel, moving up to the Linux userspace, reaching the Android framework and ending our journey with some real-life usages of Binder in Android applications. We will show how widely used Binder actually is in Android, thus proving that it is a cornerstone of the operating system. The main focus is on the programming model exposed towards developers and we will highlight when, how and why it should be used. https://bjug.ro/binding-android-piece-by-piece/

While the causes of outages are varied, human error far outpaces all hardware failures. The risk of humans touching sensitive data is clear, but the tools, techniques and risk-mitigation strategies lag behind current realities. Stephen Schmidt, AWS CISO, will share hard-earned lessons around potential gaps in your security plan, along with steps to lessen potential angles of attack. (Source: RSA Conference USA 2018)

Cosa hanno in comune un mattoncino Lego e la backdoor XZ?

Speck&Tech

ABSTRACT: A prima vista, un mattoncino Lego e la backdoor XZ potrebbero avere in comune il fatto di essere entrambi blocchi di costruzione, o dipendenze di progetti creativi e software. La realtà è che un mattoncino Lego e il caso della backdoor XZ hanno molto di più di tutto ciò in comune. Partecipate alla presentazione per immergervi in una storia di interoperabilità, standard e formati aperti, per poi discutere del ruolo importante che i contributori hanno in una comunità open source sostenibile. BIO: Sostenitrice del software libero e dei formati standard e aperti. È stata un membro attivo dei progetti Fedora e openSUSE e ha co-fondato l'Associazione LibreItalia dove è stata coinvolta in diversi eventi, migrazioni e formazione relativi a LibreOffice. In precedenza ha lavorato a migrazioni e corsi di formazione su LibreOffice per diverse amministrazioni pubbliche e privati. Da gennaio 2020 lavora in SUSE come Software Release Engineer per Uyuni e SUSE Manager e quando non segue la sua passione per i computer e per Geeko coltiva la sua curiosità per l'astronomia (da cui deriva il suo nickname deneb_alpha).
