VCAP6-DCV Design its a pass

Hi there,

after passing the VCAP Deploy exam, I successfully passed the VCAP Design exam. Thereby I am now VSphere Certified Implementation Expert Data Center Virtualization 6. (VCIX6-DCV)

Furthermore I tinker with the idea of completing the data center track. Which requires a vast expenditure both monetary and time consuming. The requirement is to successfully submit and defend an original design in front of a panel of experts. In Europe this is just possible in Staines, UK.

This process is far more complex than any other exam that exists in the IT universe. Currently there are just 264 VCDX certified people around the world, collectively over all tracks.

Along the way I prepare myself for the NCDA – Netapp Certified Data Administrator certification. Due to my participation at Insight 2017 in Berlin last week I know Netapp and Clustered Ontap will keep me occupied over the next years too. Really awesome data fabric features that will shape both private and public clouds.

Netapp Technology Forum Bavaria

 

Hello everbody,

last week on Thursday I attended a very nice event in the WWK – Arena in Augsburg. The host was Netapp and a lot of topics in form of presentations were covered. In addition I met a lot of sympathetic people.
I participated in various sessions and I listed the key facts of my favourites below:

 

Hardware and ONTAP 9.2

  • 32Gbit Fibrechannel SAN
  • 40 Gbit with 4x10Gbit break out connection
  • Hotplug Storage Controller – adding more performance – live
  • New ONTAP long term support release Modell -LTS (up to five years) and non LTS versions
  • NVE – Netapp volume encryption
  • Efficiency features
    • Aggregate (former volume) inline deduplication
    • Replication ( remote site needs more storage if inline data efficiency features are not supported )
    • Data efficiency features performance impact <10%
    • Opportunistic in nature – adaptive dedup
  • Fabric pool -> Capacity Tier -> Public or private cloud
  • QoS features in SAN
    • Min – max throughput per LUN
    • IOPs per LUN
    • Just in SAN

DevOps and Container

  • Concepts of app operation and software development
  • Standardize – consolidate – virtualize – automate – orchestrate
  • Digital innovation and transformation
  • DevOps:
    • Plan -> Develop -> Release -> Monitor -> Repeat
    • OSIMM
  • Non dynamic historic concepts replaced
  • For example: Apple release cycle – just a small part of users impacted
  • API SDK REST – Integration of common tools
  • Software defined infrastructure – environmental snapshots
  • DevOps as process of operation and development of infrastructures
  • New Job holders like “Site reliability engineer” (Google)
    • >50% Infrastructure
    • Predominant app developer
  • Container – differences to the traditional way (monolithic applications)
    • Micro services
    • Meshed over REST
    • IP based
    • Sufficient performance available nowadays
    • Can be upgraded independent
  • Concept of load balancing a.k.a horizontal scaling
  • For example: Google search engine
  • Containers are not virtual machines
  • Data storage out of the container
  • Container orchestration:
    • Kubernetes ‘k8s’
    • Dockerswarm
    • Mesos
  • Dynamic vs. persistent provisioning

GDPR – General data protection Regulation

 

  • GDPR called EU-DSGVO in Germany
  • Replaces the German “Datenschutzgesetz”
  • Affects every company which handles European personalised data or does Business with European companies
  • Will come into force on 25.05.2018
  • Save Harbour -> Privacy Shield -> GDPR
  • Company’s need additional personnel which are responsible – data protection Officer – privacy officer
  • Punishment for data leakage: up to 4% of yearly revenues or 20 million euros
  • Authorities must be informed within 72h
  • Everybody has the right to be forgotten
  • Data lineage
  • Physical location of the data must be documented
  • Data migration must be possible from one to another provider ( standardized file format, machine readable)
  • Concept of pseudonymization will be important
  • Encrypted data breach may not necessarily be reported to authorities
  • Code of conduct and certifications
  • Usage of hardening guides
