Introduction
My vision
That's my vision, it don't mean that is the future or your vision
I will not speak about what is cool in the Cloud
But about what you have to take care !

Introduction
My vision
Why Cloud adoption accelerate ?
DevOps
Why ?
> It best fit with the Cloud
> They want to test and move quickly in production
But
> Brings chaos in the migration to the Cloud
> New standard are not carefully evaluated

Introduction
Future
On-Premises database Revenue will continue to decrease
By 2022, 75% of all databases will be deployed or migrated to the cloud

Infrastructure management
Investment for an application
>Take care on detailed resource usage
> Hardware is expensive
>Server (application, database, etc..)
> Detailed configuration (CPU, memory)
>Disk configurations
> Local attached disk storage with
> Many controller
> Many disks to get the required IOPS
>Network
> Only 100Mb was available end of 90's
> Data traffic had to evaluate carefully
Application 2Application 1 Application 3

Team management
Vertical stack Model with dedicated teams for each application

Team 3

Team 2

Outcome
Results of the infrastructure ?
>Many hardware provider (HP, IBM, SUN, etc..)
>Many different server models (small, medium and big servers)
>Many different locally attached storage solution
>Many operating systems ( HPUX, AIX, SUN Solaris, etc..)
>Lots of ethernet cable connected between the switches (spaghetti)
Handing and management
>Many specialist was required
>Many partner was involved
>Complex infrastructure to manage and maintain
> Upgrade of hardware
> Patching

On-premise today
> Team management
> Outcome

On-premise today
Careful selection is less important today
>Big disks with fast answers time available (SSD, Flash)
>Multicore processor (up to 24 cores)
>NVMe card are very fast
>2Gb/s network available
However take care on proprietary software licensing model
>Oracle and MSSQL Server are based on the number of core CPU
>SAP HANA is based on amount of memory
>etc...

On-premise today
Team Management

Horizontal stack Model with dedicated teams for each stack

On-premise today
Outcome
Infrastructure standards are available for all stacks

Cloud Infrastructure today
Back to the future
Same issues as 20 years agoSame issues as 20 years ago

Resource Management
>Take care on detailed resource usage
> Price is based on consumption !
>Server configuration (application, database, etc..)
> detailed configuration (CPU, memory) AWS
You can reduce the number of
CPUs manually to be license compliant…
…You still pay for the shape’s CPUs

Disk configuration
> Cloud disks are based on IOPS
> Attach more disks to get the required performance
> Better use 2*400GB disks instead of one of 800GB

Network configuration
> Upload are free, but download must be managed carefully
> It exist different network configuration (DirectConnect at AWS)
> Detailed configuration of the buffer size will enhance the performance
Network roundtrip
>Again At least 60ms are required for a roundtrip connection to the USA
>10ms for approximately 1000km

Example with different BLOB buffer size
>Application server is located On-Premise
>Test 1 : Read from a 60 Mb BLOB (binary large object) from a database located On-Premise
>Test 2 : Read from a 60 Mb BLOB (binary large object) from a database in the Cloud
BLOB Buffer

Team management
Vertical stack Model with dedicated teams for each application
Application Team 1

Outcome
Results of the infrastructure ?
>Many Cloud provider (AWS, Oracle, Azure, Google, etc…)
>Many different server images (small, medium and big)
>Many different disk IO performance models
>Many Operating systems
>Many Cloud accounts with different security rules
Handing and management
>Many Specialist are required to manage the different Cloud providers
>Many Partner are involved
>Complex infrastructure to manage and maintain
> Upgrade of Hardware (as each service use the own images, also consequence from the DevOps growing)
> Patching (could be automated, but as many different source are used it is complex to implement it.

Recommendations
> Overview
> Landing Zone
> Landing Zone for Networking (AWS)
> Microsoft Azure
> Oracle OCI

Recommendation
Overview
Define standards
>Before deploying many Cloud Infra over many Cloud accounts
Dedicated team
>All requests must be centralized and must apply these standards
>Must be trained and have the knowledge of the used technologies
Full Cloud Application infrastructure
>Otherwise you will have to manage with performance issues between On-Premise and the Cloud
Network
>Try to minimize network traffic between the clients and the Cloud Infrastructure

Recommendation
Landing Zone
What is a Landing Zone ?
>Is not a service
>Is a solution to helps quickly set up a secure environment based on best practices
>Include the core components of your Cloud Infrastructure
>It should be well thought out and strategized
Standardize

>Network infrastructure managed by Network Admins
>Resources: VCN, Security lists, Internet gateways, DRG's
Compartment : Dev, Test, Prod Network
>compartment to easily write policy about the network usage
>Resources: Subnets, Databases, Storage (if shared)
Compartment : Projects
>Resources used by a particular team or project
>Resources : Compute Instances, Databases, Block Volumes, etc
>One per team that needs it's own environment
