Several key technology trends are redefining the boundaries of the traditional storage infrastructure stack: In a rapidly changing world of system interconnects, emerging memory media, and storage semantics, Server Designers and Storage Architects are engaging and collaborating like never before to exploit breakthrough technology capabilities.
With the backdrop of Big Data volume, Cloud Data ubiquity and IoT Data velocity, Application Developers are entering the Post-POSIX world of real-time, high-frequency, low latency data management frameworks.
This session will address key technology trends in Storage, Networking, and Compute, as they define the parameters of a Memory Centric Architecture (MCA) and the Next Generation Data Center.
Adaptive Computing Using PlateSpin OrchestrateNovell
Adaptive computing goes beyond just intelligently utilizing available resources; it encompasses quality of service (QoS) targets, fault tolerance (high availability), monitoring, and iterative analysis of the resulting dataset to determine what corrective measures (adaptations) should occur at any given moment. As virtualization becomes widespread in the data center, the need for automating the placement and configuration of workloads (virtual machines) using an adaptive computing model becomes vitally important. This session demonstrates how to use events, introduced in PlateSpin Orchestrate 2.0.2, to create rules that trigger workload provisioning, migration, and other virtual machine lifecycle operations. It will also offer a preview of new functionality included in the upcoming 2.1 release of the product.

BACK FROM THE EDGE: INFRASTRUCTURE PROTECTION THROUGH PLATESPINMicro Focus
Stuff happens and every organization needs effective
disaster recovery plans for key IT infrastructure
components. Doing nothing is not an option, clustering
is not cost-effective for all workloads, and tape
backups just take too long to restore. So what are
your options? In this session we’ll take a look at how
virtualization technology can help fill the gap with costeffective
recovery of important server workloads.
The talk belonging to this slide deck is basically a "sequel" of the "Patterns of resilience" talk. It briefly repeats a few core statements of the previous talk and then starts to complete the picture.
First, it creates a more complete pattern taxonomy and locates the taxonomy of the previous talk in it. Then, it repeats a few of the patterns of the first talk concerning core architectural patterns and error detection patterns, enriching them with some additional information.
After that the core part of this talk starts: The error recovery and error mitigation patterns. The talk presents several well known and not so well known patterns from those two domains, partially augmented with code examples. Then after, briefly touching fault treatment patterns, some more patterns of the error prevention domain are presented.
The talk concludes with a small guideline, how to identify the appropriate pattern set for a concrete situation.
As always, the voice track and therefore a lot of information is missing in this slide deck. Yet, I hope that it provides a few helpful pointers.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige 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:

process, policies and
procedures related to
preparing for recovery
or continuation of
technology
infrastructure critical to
an organization after a
natural or human-
induced disaster.”

14. Designing a Highly Available System
• Which level of High Availability do I need?
• Do I require no loss of data?
• Do I need failover or is switchover enough?
• Can I provide a reasonable service when a
component is down?

15. Something to clarify...
• Availability vs Scalability
• HA Costs
• HA for your systems, not only for your
database
• Review your SLAs

18. MySQL Replication
• Something you may have missed...
–Asynchronous or Semi-synchronous
–Pros and Cons of RBR vs SBR
–Mono-thread pull from
the slaves
–sync_binlog = 0/1
–Antilope vs Barracuda Read-Write
–Group Commit Read-Only Read-Only
–Multi-engines
–Rolling upgrades binlog

28. Active/Passive Clusters using
Shared Storage
• Points to consider: Active/Hot Passive/Std-by
–Redundancy and replication Server Server
must be guaranteed by
the shared storage
(and this is not trivial)
–InnoDB only
–File Systems
Shared
Storage 28

31. Virtualised Environments
• Data storage, high availability and load balancing are
provided and managed by the virtualised software
• In case of fault, the virtualised software restarts on
any other
physical
server
• MySQL Replication

32. Geographical Replication for Disaster
Recovery
• Master-Master Asynchronous
Replication is used to update the
backup data centre
• In case of fault, the network
traffic is redirected to the
backup data centre. Failback
must be executed manually
• Cross-platform and cross-
engine

33. Storage Snapshots for Disaster
Recovery
• Snapshots are managed by the NAS and SAN
firmware. There is usually a short read-only freeze

34. MySQL Cluster
• Shared-nothing, fully transactional and distributed architecture used for high volume and
small transactions.
• MySQL Cluster is based on the NDB (Network DataBase) Storage Engine
• Data is distributed for scalability and performance, and it is replicated for redundancy on
multiple data nodes.
Application Nodes
• Nodes in a cluster:
– SQL Nodes: provide the
SQL interface to NDB
– API Nodes: provide the
native NDB API
– Data Nodes: store and
retrieve data, manage
NDB API, ClusterJ/JPA
SQL Nodes
transactions
– Management Nodes:
manage the Cluster
• Load balanced
• Memory or disk-based
• Geographically replicated
for disaster recovery with
conflict resolution
• Full online operation for
maintenance and Management
administration Nodes

35. Client-based Failover and Proxies
• Connector/J
–jdbc:mysql://[host][,failoverhost...][:port]
• mysqlnd_ms for PHP
–connection pooling for mysqli, mysql and
PDO_MYSQL
• ScaleBase

37. The famous last words...
• I need 5 nines
–
• Everything must be automatic
–
• I want to migrate to MySQL Cluster
–
• I can’t afford to lose any data
–
• I need a sub-second failover

38. The famous last words...
• I need 5 nines
–Implement what you really need
• Everything must be automatic
–Aided switchover is sometimes more effective,
inexpensive and easy to implement/administer
• I want to migrate to MySQL Cluster
–Is your application designed for Cluster?
• I can’t afford to lose any data
–People lose data every day. Is the drop in
performance worth it?
• I need a sub-second failover
–Check the timeout periods and the caching warm-
