Docker in the Real World
Overview
JAMES SCHORR

The ”Why”
• Real-world issues / concerns
• Reliability
• Scaling
• Testing
• Deployments
• Environment “drift”
• Day 2 Operations (patching, logging, metrics,
troubleshooting)

The “What”
• Easier to scale
Replace rather than patch
• Discrete units
• Dependency understanding
• Boundaries defined
• Deployments: blue-green, rollback
strategies, canary, etc…
• Consistency
• Isolation
• Portability
• Developer on-boarding / transitions

Container-Centric SDLC
Overview
• Cost
• Impact:
• Developers
• Infrastructure
• DR
• Silo breakdowns
• Portability
• Repositories
• SCM
• Scalability
• Technical debt strategies

Container-Centric SDLC
Paradigm Changes
• Development
• Dependencies
• Deployment: CI/CD pipelines vs “legacy”
• Microservices
• State
• Operations
• Issue Resolution
• Metrics
• Reporting
• Scaling
• Security Remediations

Typical disaster recovery plans leverage backup and/or replication to move data out of the primary data center and to a secondary site. Historically, the secondary site is another data center that the organization maintains. But now, companies are looking to the cloud to become a secondary site, leveraging it as a backup target and even a place to start their applications in the event of a failure. The problem with this approach is that it merely simulates a legacy design and presents some significant recovery challenges.

Achieve development agility, improve run-time application resiliency, and deliver highly-responsive applications by adopting cloud-native design patterns and building cloud-aware applications. Forklifting applications into the cloud is relatively fast, but the simple path into the cloud does not create better software. End-users may still complain about your development velocity, operations may still struggle to maintain uptime guarantees, and development iterations may continue at a glacial pace. By iteratively applying cloud-native design patterns and re-architecting applications, teams reduce technical debt, deploy with confidence, and build highly scalable solutions. Cloud-aware applications embrace microservices, actor model interactions, map-reduce processing, shared-nothing architecture, and the thirteen dwarf patterns. Learn about cloud-native design practices and frameworks that help you optimize scalability, foster anti-fragility, and decompose application monoliths into cloud-native microservices. Chris describes how Kubernetes, Akka, Hadoop, Eureka, Hysterix, and other open source projects make cloud-native design and implementation an approachable proposition.

System Center Service Manager 2010, released last May, integrates with other System Center and third party products to provide ITIL and Microsoft Solutions Framework aligned processes and practices for incident management, change management, and deployment management. But don’t get confused. It’s not a help desk! Using workflows, integrated configuration items, and reporting and tracking you can manage the services in your organization to create a more dynamic, reliable environment for your organization. View the slide deck and explore the benefits of Service Manager with Jason Sharp, C/D/H's Infrastructure Service Lead, and a regional expert in systems management solutions. Contact C/D/H for more information about this and other topics – or check our blog at www.cdhtalkstech.com for tips on Systems Center and other technologies.

Enterprise Architecture (EA) provides a visual blueprint of the organization, and shows key interrelationships between data, process, applications, and more. By abstracting these assets in a graphical view, it’s possible to see key interrelationships, particularly as they relate to data and its business impact across the organization. Join us for a discussion on how data architecture is a key component of an overall enterprise architecture for enhanced business value and success.

Rightscale Webinar: The number one cause of poor scalable web application performance is the database. This problem is magnified in cloud environments where I/O and bandwidth are generally slower and less predictable than in dedicated data centers. Database sharding is a highly effective method of removing the database scalability barrier by operating on top of proven RDBMS products such as MySQL and PostgreSQL. In this webinar, you'll learn what it really takes to implement sharding, the role it plays in the effective end-to-end lifecycle management of your entire database environment, and why it is crucial for ensuring reliability. In this webinar, we will: - Guide you on how to choose the best technology for your specific application - Show you how to shard your existing database - Review a case study on a Top 20 Facebook application built on dbShards

Most large-scale web companies have evolved their system architecture from a monolithic application and monolithic database to a set of loosely coupled micro-services. Using examples from Google, eBay, and KIXEYE, this talk outlines the pros and cons of these different stages of evolution, and makes practical suggestions about when and how other organizations should consider migrating to micro-services. It concludes with some more advanced implications of a micro-services architecture, including SLAs, cost-allocation, and vendor-customer relationships within the organization.
