MongoDB SF Ruby
MongoDB presentation for SF Ruby's June meetup. Review of non-relational databases for the first half, focus on MongoDB for the second.
Building a Database for the Future with MongoDB Atlas
This document provides an overview and introduction to MongoDB Atlas, which is MongoDB's database as a service offering. Some key points:
- MongoDB Atlas allows users to run MongoDB in a fully managed, cloud-based environment without having to manage infrastructure themselves.
- It offers global availability across 14 AWS regions, high availability across availability zones, security by default, comprehensive monitoring, and managed backups.
- Using MongoDB Atlas reduces the total cost of ownership compared to self-managed deployments and accelerates time to value by removing the operational overhead of database management.
- Features include cross-region replication for disaster recovery, security isolation using VPC peering on AWS, encryption of data both in-flight and at-rest
Yipit - AWS Start-Up Customer
Yipit is the largest daily deal aggregator in the US with 20 employees and 40+ servers hosted on AWS. It was built using Python, Django, Nginx, Gunicorn, Celery, MySQL, MongoDB, Redis and DynamoDB. AWS services currently used include S3, EC2, CloudWatch, CloudFront, RDS, ElastiCache, SQS, IAM, Route53 and DynamoDB. AWS provides benefits like speed of iteration, infrastructure as code, leveraging AWS expertise, and automation which helps Yipit as a startup. Yipit monitors its infrastructure using New Relic, Django Sentry, Papertrail, AppFirst and Stathat.
How we build Videome
This document discusses how to build scalable and stable web applications using VME. It focuses on measures for scalability including using distributed databases like MongoDB, message queues for logic decoupling, and stateless microservices for frontends and backends. It also covers high availability through techniques like MongoDB replication, RabbitMQ HA, and web server clusters. Additionally, it outlines the importance of automation through testing, DevOps, and containers, as well as comprehensive monitoring of availability, performance, errors, and alerts.
Migrating Data Pipeline from MongoDB to Cassandra
MongoDB is a great NoSQL database, it’s very flexible and easy to use,
but would it handle massive Read / Write throughput?
actually, what happens when you need to scale everything out and easily?
We will lay out the reasons and the steps of migrating our data pipeline to Apache Cassandra in a short period without having any prior knowledge.
We’ll list our lessons learned as well.

Hyperloglog Lightning Talk
The document discusses using the Hyperloglog algorithm and Redis to approximately count unique items in a dataset in a space-efficient way. Some key points:
- Hyperloglog is an algorithm that estimates the size of a set in a space-efficient manner, sacrificing some accuracy.
- It provides a similar interface to a set but uses much less space (around 12kb) while maintaining the same time complexity.
- Redis implements Hyperloglog which allows approximating uniques across programming languages and persisting counts to the Redis key-value store in a space-efficient way.

The evolving container landscape
This document discusses the evolving container landscape and how applications are becoming cloud native. It outlines how companies are increasingly relying on technology and how software development has focused on continuous development, integration, and deployment. Open source adoption is growing as the default choice for developers. The document then examines the container technology stack from infrastructure to applications and services. It analyzes challenges around enterprise adoption and providing standard comparisons. Finally, it discusses how containers need to address security, storage, networking and other issues to become truly enterprise-grade.
Being Stateful In Kubernetes
This Knolx session discusses how stateless and stateful applications can be deployed over Kubernetes using Stateful Sets. In the demo, we see how requirements for stateful services could be met and how Cassandra, a stateful service could be started over Kubernetes
Dynomite - PerconaLive 2017
Netflix created and open sourced Dynomite project to provide reusable distributed database infrastructure that turns single server data stores into scalable, distributed databases. Dynomite supports pluggable protocols and pluggable storage engines, which allows us to add sharding and replication to a variety of non-distributed data stores. The entire database infrastructure can be reused across a variety of workloads from in-memory to on-disk, and across APIs from key/value to document databases. Dynomite allows application developers to choose the API that best fits their requirements, while DevOps can select the best operation database based on the workload. Dynomite is used by Netflix to handle millions of OPS in production leveraging Redis and RocksDB. In this talk, we are going to show how we achieved high availability by being able to terminate any Dynomite node without client side downtime, best practices and the challenges in deploying Dynomite in production.
Going Serverless
A simple traditional web application consists of a web server, web client and an optional database. A traditional software developer needs to be aware of the server in which his code runs, because it has to be created, scaled, and maintained. If it goes down at the most critical time, it could result in drastic consequences.
When a single application is deployed in a server, there will be lot of unused resources. For example, if a developer deploys a Storm cluster which uses CPU heavily for computation, there will be less use of the hard disk. These servers are not custom made for our applications so there will be resource wastages. The concept of a Serverless Architecture came up as a solution to overcome this problem and a lot of other issues coupled with physical servers. In this Innovation Session, Danula Eranjith, Malinga Perera and Shehan Perera from the Data and Analytics team discuss the Serverless Architecture concept, and how it can be implemented using AWS technologies.
Briefing: Containers
Containers seem to have suddenly become the hot new thing everyone is talking about, but what are they?
Why are they important?
How should you use them and what does it mean for cloud infrastructure? This talk will examine the history, technical details and strategy around containerisation from the perspective of developers and operations, consider internal container OSs like Rocket and Ubuntu Core as well as management layers like Docker and Apache Mesos and take a look at why cloud providers are launching their own services around them.
Presented by David Mytton at Datacloud Monaco 2015-06-04
Cncf storage-final-filip
This document provides an overview of cloud native storage. It discusses how storage is a key component of cloud native reference architectures and how container-based applications require persistent storage volumes. It introduces the concept of out-of-tree storage plugins that allow various storage platforms to integrate with container orchestrators. The document also outlines common cloud native storage patterns, such as giving containers persistent volumes, and how this enables portability across infrastructure providers. Finally, it provides examples of how storage classes, persistent volumes, and persistent volume claims can be used to provision storage for pods running in containers.
Travis
This document lists various database technologies that can be integrated with Travis CI such as MySQL, PostgreSQL, MongoDB, CouchDB, Redis, Riak, RabbitMQ, Memcached, Cassandra, Neo4J, ElasticSearch, Kestrel, and SQLite3. It also mentions configuring integrations using a .travis.yml file and gaining profits from such integrations.
Loadbalancers: The fabric for your micro services
The document discusses the importance of load balancers for microservices and container-based architectures. It covers how load balancing needs have evolved from traditional monolithic applications to modern approaches that support dynamic microservices topologies, zero-downtime deployments, client-side load balancing, and advanced patterns like circuit breakers. It also introduces NetScaler CPX as a cloud-native load balancer solution for container environments.

The NoSQL Ecosystem
The document discusses the NoSQL ecosystem. It provides a brief history of NoSQL databases from the late 1990s to today. It then lists and categorizes the major NoSQL databases. The rest of the document discusses interesting properties of NoSQL databases like data models, query models, transactions, and consistency. It also provides examples of real-world usage at companies like Netflix, Facebook, and Craigslist. Key takeaways are around developer accessibility, reuse of NoSQL components, and using the right tool for the job (polyglot persistence).
HPTS 2011: The NoSQL Ecosystem
My talk for HPTS 2011, summarizing the NoSQL ecosystem and what systems builders can learn from NoSQL's success.
It's in the cloud
The document discusses provisioning and how the pkgcloud package can help with provisioning for the cloud. Pkgcloud is a multi-cloud provisioning package for node.js that provides a single convention for working with multiple cloud providers and abstracts out the peculiarities of individual provider APIs. Rackspace is involved with pkgcloud because it aims to engage with existing open source communities rather than fragment them and already has committers on other open source cloud libraries.
Survey of High Performance NoSQL Systems
Learn the current state of the NoSQL landscape and discover the different data models within it. From document stores and key value databases to graph and Wide Column. Then you’ll learn why wide column databases are the most appropriate for scalable high performance use cases, including capabilities for massive scale-out architecture, peer-to-peer clustering to avoid bottlenecking and built-in multi-datacenter replication.

SQL, NoSQL, NewSQL? What's a developer to do?
The database world is undergoing a major upheaval. NoSQL databases such as MongoDB and Cassandra are emerging as a compelling choice for many applications. They can simplify the persistence of complex data models and offering significantly better scalability and performance. But these databases have a very different and unfamiliar data model and APIs as well as a limited transaction model. Moreover, the relational world is fighting back with so-called NewSQL databases such as VoltDB, which by using a radically different architecture offers high scalability and performance as well as the familiar relational model and ACID transactions. Sounds great but unlike the traditional relational database you can't use JDBC and must partition your data.
In this presentation you will learn about popular NoSQL databases - MongoDB, and Cassandra - as well at VoltDB. We will compare and contrast each database's data model and Java API using NoSQL and NewSQL versions of a use case from the book POJOs in Action. We will learn about the benefits and drawbacks of using NoSQL and NewSQL databases.
Apache Cassandra in the Real World
Apache Cassandra is a highly scalable, multi-datacenter database that provides massive scalability, high performance, reliability and availability without single points of failure. It is operations and developer friendly with simple design, exposed metrics, and tools like OpsCenter and DevCenter. Cassandra is used by many large companies including Netflix to store film metadata and user ratings, La Poste to store parcel distribution metadata, and Spotify to store over 1 billion playlists.

- In Kubernetes, PXC nodes would be deployed as pods with a replication controller to maintain a set number of pods. Services provide load balancing to the pods.
- Demonstrated deploying a basic PXC cluster on Kubernetes, including creating a network, cluster, service, replicating pods from a template, and exposing ports.
- Challenges include load balancing for state transfers between nodes and ensuring nodes are
Working from home - fun, facts and scares!
Gone are those days when companies used to be strictly colocated in a single office. Distributed workplaces are gradually becoming the norm than an exception. So, it is essential that we talk more about it and discuss it.
So, this talk is essentially about:
a) Productivity and working from home.
b) Scheduling flexibility.
c) Challenges in communication and ways to overcome them.
d) Ways of getting such a job and Open Source.
e) Measuring work and micro-management
f) Feeling of detachment and workarounds for it.

Securing databases with systemd for containers and services
Data is the most valuable entity associated with a system, particularly when it is a sensitive one. Not only are there threats associated with physical access
to the box, but also ones where logical access suffices - sql injections etc.
Vulnerabilities like shellshock and heartbleed have also shown that an exploit in one component can also be used to access others through buffer overflows, memory overruns etc. and/or impact the immunity of system severely.
This is where "Principle of least privilege" comes into play. Wikipedia defines it as "a particular abstraction layer of a computing environment, every module (such as a process, a user or a program depending on the subject) must be able to access only the information and resources that are necessary for its legitimate purpose".

UI5con 2024 - Bring Your Own Design System
How do you combine the OpenUI5/SAPUI5 programming model with a design system that makes its controls available as Web Components? Since OpenUI5/SAPUI5 1.120, the framework supports the integration of any Web Components. This makes it possible, for example, to natively embed own Web Components of your design system which are created with Stencil. The integration embeds the Web Components in a way that they can be used naturally in XMLViews, like with standard UI5 controls, and can be bound with data binding. Learn how you can also make use of the Web Components base class in OpenUI5/SAPUI5 to also integrate your Web Components and get inspired by the solution to generate a custom UI5 library providing the Web Components control wrappers for the native ones.
