1. The document discusses the evolution of caching strategies at Build.com as their systems and traffic grew rapidly over time. They initially used a Java-based distributed cache and later switched to Redis which proved more effective.
2. As Build.com moved to a continuous delivery model with multiple environments, they needed a "shared" cache that both environments could use. They implemented a unified caching model where each version of code has its own bucket in the cache but objects can be promoted from older versions if they are compatible.
3. The key aspects of the unified caching model are using a serialization checksum to detect changes between versions, using a build number as the cache key so each version is separate, and attempting to promote
Making Friendly Microservices by Michele TitlolDocker, Inc.
Small is the new big, and for good reason. The benefits of microservices and service-oriented architecture have been extolled for a number of years, yet many forge ahead without thinking of the impact the users of the services. Consuming on micro services can be enjoyable as long as the developer experience has been crafted as finely as the service itself. But just like with any other product, there isn’t a single kind of consumer. Together we will walk through some typical kinds of consumers, what their needs are, and how we can create a great developer experience using brains and tools like Docker.

Containerized Databases for Enterprise Applications
Containers are now being used in organizations of all sizes. From small startups to established enterprises, data persistence is necessary in many mission critical applications. “Containers are not for database applications” is a misconception and nothing could be further from the truth.
This session aims to help practitioners navigate the minefield of database containerization and avoid some of the major pitfalls that can occur. Discussion includes traditional enterprise database concerns surrounding data persistence and data security, and how they mesh with containerized deployment.
Container technology is shaping the future of software development and is causing a structural change in the cloud-computing world. Developers are embracing container technology and enterprises are adopting it at an explosive rate. Containers are portion of "IT" in technology as they're a very powerful tool which streamline your development and ops processes, save company's money & make life for developers much easier.

Building a Secure Supply Chain with DockerDocker, Inc.
Creating a Secure Supply Chain of images is vitally important. Every organization needs to weigh ALL options available and understand the security risks. With so many options for images, it is tough to pick the right ones or even to create your own. Ultimately, every organization needs to know the provenance of all the images. Then once the images are imported into the infrastructure, a vulnerability scan is vital. Docker Trusted Registry with Image Scanning will give organizations insight into any vulnerabilities. Better yet, its automated with a succinct audit trail, so you can still take that vacation you had planned and make your security team happy.

Cloud-Native Fundamentals: Accelerating Development with Continuous IntegrationVMware Tanzu
DevOps. Microservices. Containers. These terms have a lot of buzz for their role in cloud-native application development and operations. But, if you haven't automated your tests and builds with continuous integration (CI), none of them matter.
Continuous integration is the automation of building and testing new code. Development teams that use CI can catch bugs early and often; resulting in code that is always production ready. Compared to manual testing, CI eliminates a lot of toil and improves code quality. At the end of the day, it's those code defects that slip into production that slow down teams and cause apps to fall over.
The journey to continuous integration maturity has some requirements. Join Pivotal's James Ma, product manager for Concourse, and Dormain Drewitz, product marketing to learn about:
- How Test-Driven Development feeds the CI process
- What is different about CI in a cloud-native context
- How to measure progress and success in adopting CI
Dormain is a Senior Director of Product and Customer Marketing with Pivotal. She has published extensively on cloud computing topics for ten years, demystifying the changing requirements of the infrastructure software stack. She’s presented at the Gartner Application Architecture, Development, and Integration Summit; Open Source Summit; Cloud Foundry Summit, and numerous software user events.
James Ma is a product manager at Pivotal and is based out of their office in Toronto, Canada. As a consultant for the Pivotal Labs team, James worked with Fortune 500 companies to hone their agile software development practices and adopt a user-centered approach to product development. He has worked with companies across multiple industries including: mobile e-commerce, finance, heath and hospitality. James is currently a part of the Pivotal Cloud Foundry R&D group and is the product manager for Concourse CI, the continuous "thing do-er".

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

6. Started as a single web site
The site and company grew rapidly
Even the CEO helped with coding (oh dear)
Deployment were done at night
Performance issues
7. There were several distributed
caching options
We tried a Java-based distributed
cache first
We decided to use Redis
Caching?
Round 1 - Fight!
https://pixabay.com/users/12019-12019/?utm_source=link-attribution&utm_medium=referral&utm_campaign=image&utm_content=115800
8. It’s hard to argue with the results
Why Redis?
Redis can be clustered
Redis is blazingly fast
Easy to maintain/upgrade
Built-in support in for Spring.
9. Introducing a cache proved very effective.
We did deployments at night
Deployment meant purging the cache
It worked for a while
And we continued to grow
Caching To Rescue
https://pixabay.com/vectors/superhero-super-hero-hero-figure-304713
Distributed
Cache!
10. Multiple web storefronts
We put more data into cache
Sites were really slow after deployment
We introduced cache priming
Held our breath as morning arrived
We need to fix this!
We Are Killing Ourselves
Story Time
https://pixabay.com/vectors/superhero-super-hero-hero-figure-304713
11. Two identical environments (prod./dark)
Both environments use the same data stores
Deploy to the dark servers in the day
Still had to purge and prime the cache
Blue / Green Deployments
17. Push code to production often
Changes are smaller/less risk
Immediate user feedback
Continuous Delivery
Automate the process
Monitor for issues
Need the ability to rollback
https://harness.io/
19. The Trouble Spots In Rolling Deployment
System must be resilient to having two versions of your application running concurrently.
Both versions of the application need to play nice when they are sharing a cache.
21. The application is caching customer data
Version 1 has basic customer object
Version 2 adds address information to the
customer
Demo Setup
Round 2 - Fight
(and a demo?)

https://github.com/tkvangorder/redis-shared-cache-sample
22. What can go wrong?
https://github.com/tkvangorder/redis-shared-cache-sample
27. Cache Promotion
Version cache miss, look for another version’s copy
If the checksum is successful, copy is compatible
Promote that copy into cache for the new version
https://github.com/tkvangorder/redis-shared-cache-sample
28. PRESENTED BY
1 Use a serialization checksum
The use of an incrementing uid for each complex object insures changes to nested objects are also
detected. This requires a change in the development process!
2 Use a build number as your nested hash key
Each active build will have it’s own version of a cached object. Automate the injection of this build
number into your software artifacts!
3 Attempt a cache promotion on a cache miss.
If a new build does not have a copy of the cached value, attempt to deserialize the previous version. If
there are no structural changes, promote!
Summary:
29. PRESENTED BY
1 What about cache eviction?
The root key is still pinned to the record, eviction in one version will evict ALL copies.
2 Time to live helps manage the overall resource requirements
Multiple copies of the same object requires more resources for you Redis cluster. In practice, we have
found this to be a non-issue in our environment.
3 We have written the unified cache implementation twice
We originally extended the default Redis cache implementation in Spring Boot 1.5.x, now we have our
own cache implementation.
Final Notes:
4 Open Source?
All of the sample code, including the unified cache library demonstrated here are available for your
use. If there is enough interest, we may make an official open source offering.
