2 likes•1,196 views

Over the past year, more and more Java applications have benefited from gaining access to elastic, cloud-ready, data grids thanks to Infinispan, and from now on, Ruby apps running within TorqueBox get the same benefit as well thanks to the ability of TorqueBox to talk to Infinispan Hot Rod servers. In this talk, Galder will demo the integrations between TorqueBox, which is a Ruby application plattform, and Infinispan, which is a Java based data grid plattform, highlighting the benefits for TorqueBox administrators and Ruby developers, which include, amongst others, access to highly-scalable, low-latency data store that avoids single point of failure.

Data Grids vs Databases

Galder Zamarreño

This document summarizes a presentation about data grids versus databases. It discusses how data grids provide extremely fast in-memory access to distributed data and can be used for caching to improve database performance. While data grids offer benefits like scalability, their use requires a different programming model than databases. They may replace databases for some use cases like analytics but databases will remain important for their maturity and existing implementations. Data grids are best viewed as complementing rather than replacing databases.

Data Grids and Data Caching

Galder Zamarreño

Galder Zamarreño from Red Hat presented on Infinispan, an open source in-memory data grid platform. Infinispan can be used as a local cache, clustered cache, or as a data grid. As a data grid, it provides a highly available, distributed, and elastic data store. Infinispan also enables users to build their own data-as-a-service solutions in private clouds by virtualizing data and making it accessible in an elastic and scalable manner. Major companies use Infinispan both as a cache (e.g. for Hibernate) and as a data grid for applications requiring real-time access to distributed data.

Matias Paterlini

2013 - Matías Paterlini: Escalando PHP con sharding y Amazon Web Services

PHP Conference Argentina

The document discusses scaling a PHP application using database sharding and Amazon Web Services. It describes using MySQL databases sharded across multiple database servers to improve scalability. Key points include using an application driver to determine which shard to write to, caching static files and data, and leveraging various Amazon services like S3, EC2, CloudWatch, and Route 53. Benefits of this approach include smaller, faster databases that are easier to manage and scale out writes by adding additional database shards.

Building A Scalable Open Source Storage Solution

Phil Cryer

The Biodiversity Heritage Library (BHL), like many other projects within biodiversity informatics, maintains terabytes of data that must be safeguarded against loss. Further, a scalable and resilient infrastructure is required to enable continuous data interoperability, as BHL provides unique services to its community of users. This volume of data and associated availability requirements present significant challenges to a distributed organization like BHL, not only in funding capital equipment purchases, but also in ongoing system administration and maintenance. A new standardized system is required to bring new opportunities to collaborate on distributed services and processing across what will be geographically dispersed nodes. Such services and processing include taxon name finding, indexes or GUID/LSID services, distributed text mining, names reconciliation and other computationally intensive tasks, or tasks with high availability requirements.

soft-shake.ch

This document summarizes a presentation given by Galder Zamarreño on data grids versus databases. The presentation discusses how data grids provide extremely fast access to in-memory data and how they are suitable for scaling applications horizontally. It also covers how data grids can be used to cache database access for improved performance or potentially replace databases for certain use cases requiring high speed and scalability. However, databases are still necessary for many applications and both data grids and databases each have their appropriate use cases.

Interop 2011 - Scaling Platform As A Service

Patrick Chanezon

Most enterprise cloud adoption has relied on virtual machines and infrastructure as a service. However, there is a lot to love about the other approach to clouds—platform as a service. In a PaaS model, you worry about your code, and the systems take care of the rest. True Platform-as-a-Service not only reduces the cost of hardware infrastructure, but also reduces the complexity of the software stack that runs on it. PaaS promises to trim development and deployment time from months and years to days and weeks, but what are the signs of a true PaaS powerhouse? Is it simply free of servers or software to manage? Does it provide automatic upgrades and elasticity? Can you develop in multiple languages and across multiple device platforms? Many informed analysts think PaaS is the inevitable consequence of true utility computing. In this session, Patrick Chanezon of VMWare explains why PaaS may be the future of the enterprise.

Optiq: A dynamic data management framework

Julian Hyde

Optiq is a framework that allows heterogeneous data from different locations and formats to be queried using a standard SQL interface. It helps optimize queries by caching results, pre-computing aggregates, and using column-oriented storage and materialized views to speed up analytics queries on large datasets. By treating different data sources as a single database and helping "cheat" through query optimization techniques, Optiq provides the benefits of a centralized database for managing and querying hybrid transactional and analytical workloads.

Proud to be polyglot!

NLJUG

The document discusses the benefits of using a polyglot approach to application development.

Addressing vendor weaknesses in user space (Robert Treat)

Ontico

The document discusses how Postgres deals with bloat caused by its MVCC architecture. Postgres uses MVCC to allow for high concurrency even during read/write activity by keeping track of transaction counters for rows. This leads to dead rows accumulating over time. Postgres uses Heap-Only Tuples (HOT) to do on-the-fly cleanup of updated rows and VACUUM for bulk cleanup, but these have limitations for dealing with bloat.

Hive spark-s3acommitter-hbase-nfs

Yifeng Jiang

- The document discusses running Hive/Spark on S3 object storage using S3A committers and running HBase on NFS file storage instead of HDFS. This separates compute and storage and avoids HDFS operations and complexity. S3A committers allow fast, atomic writes to S3 without renaming files. Benchmark results show the magic committer is faster than the file committer for S3 writes. HBase performance tests show FlashBlade NFS providing low latency for random reads/writes compared to Amazon EFS.

Building Complete Private Clouds with Apache CloudStack and Riak CS

John Burwell

IT infrastructure rigidity has emerged as one of the leading barriers to achieving the cost efficiency and operational agility required to drive growth. While public cloud such as Amazon Web Services and Rackspace provide this agility, many organizations are precluded from utilizing them due to regulatory, security, performance, and/or existing investments. For these organizations to realize these agility benefits, they must transform their private infrastructures to embrace public cloud principles. During this session, we will explore cloud system architecture principles and best practices. Using the Apache CloudStack cloud orchestration platform and Basho’s Riak CS object store, a complete, open source private cloud will be realized that creates the operational agility and cost-reduction benefits of public clouds.

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).

Alt. GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using ...

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.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf

Paige Cruz

Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack. While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack. I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
