Transformation Advisor Rule examples
21
Category Rule
1 Dev (WAMT rules) Functional code assessment of application binaries by WAMT to determine which source and target WAS
editions/versions have what technical compatibility issues.
2 Dev Assign dev costs to each application issue / issue category detected by WAMT. Call out high cost
thresholds at issue and total cost level.
3 Dev Which legacy WAS versions should not be considered for migration at all because they have prohibitive
refactoring cost.
4 Dev Functional assessment to determine whether embedded messaging in ICp Liberty (or tWAS SIBus) can be
used or we need full messaging solution.
5 Performance Determine ideal location of a DB connected to the application - in Cloud or keep where it exists depending
on user pref, usage frequency, size and any other performance attributes.
6 Performance Max number of network hops between a DB and application depending on criticality of data access and
usage frequency.
7 Performance Determine whether embedded messaging should be used in ICp Liberty based on usage and other
performance requirements.
8 Performance Max number of network hops between application and messaging depending on usage frequency and
latency requirements.
9 Performance Depending on application container dependencies and latency requirements, co-locate the containers in
same network.
10 Performance Determine sizing of containers depending on user inputs and in future usage data.
11 Performance Determine number of container replicas in ICp for load balancing
12 Availability Determine number of container replicas in ICp for recovery.
13 Security Anti-Colocation constraints between containers
14 Security Which application containers need in / outbound access (external dependencies)
15 Security Determine location of the DB in Cloud or where it exists depending on data security
* each rule can have a cost implication, e.g. replicas and anti-colocation of containers can increase cost

Security
Or, why most enterprise still prefer private cloud

32. IBM Systems
Primary goal is to provide visibility, control, and analytics permitting a to assess and enforce
security and compliance of their applications and data running in the cloud
• When workloads are deployed as containers, container layer is a natural place where such visibility and
control should be provided
• Focus on applications and data, not infrastructure – application-centric visibility and control
Applications and data is what users care about – regardless of the infrastructure
Active area of innovation and start-up investment
• A new approachemerging: declarative, portable, DevOpsfocused
Several Research assets and activity in this area
32
By providing flexible, application-centric visibility and control security services in container layer on a fully-
managed container platform, we can leapfrog security advantage of our competitors.

Storage
Persistent volumes, storage classes, supported
storage connectivity

44. IBM Confidential
Storage
• Persistent Volume
Networked storage in a cluster that is
provisioned by an administrator
• Persistent Volume Claim
A request for storage that is made by a user
• Storage Classes
A label used to identify, and dynamically
create, specific qualities of storage to use.
(“ibmc-file-silver” for higher-intensity
workloads compared to “ibmc-file-bronze”)
• Storage Options
VMware datastore, GlusterFS, Spectrum
Scale, (including defaults for NFS, HostPath)

45. IBM Confidential
Storage Example
• Helm chart specs
Service declares what persistent volume it will “claim”. In this
case, a ReadWriteMany volume with the size and storage class
specified in the parameters set by the user.
• Clients can customize
A set of variables that will show up in the UI (or customized at the
helm command line). Notice here it will claim a persistent volume
of any storage class of 2GB or more.
• UI showing variables
DB2 storage options where admin can choose “Claim 10GB of
storage for this instance of Db2”. Admin could create custom
“gold” storage class so it will use best storage for this instance.
• Persistent Volume
Admin pre-creates PV that matches, or sets up to dynamically
create.
Deployment Chart (View online)
Values.yaml file (View online)

46. IBM Confidential
Storage Classes – Example
• Dynamic Provisioning
Storage classes can map to a “provisioner” to
dynamically provision persistent volumes based
on the volume claim requests coming in as users
deploy workloads and services.
• Map to Storage
IBM Cloud private supports the following for
dynamic provisioning,abstracts details so the
user doesn’t need to take multiple steps to
acquire, bind, and claim storage for their app:
• GlusterFS learn more
• VMware vSphere volumes learn more
• Change Default Storage Class
A default storage class can dynamically provision
storage when a storage class is not specified.

kubectl get storageclass
#set current default to “false”
kubectl patch storageclass default-class-name -p '{"metadata":
{"annotations":{"storageclass.kubernetes.io/is-default-class":"false"}}}’
#set your desired default to “true”
kubectl patch storageclass gold -p '{"metadata":
{"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'
Change default storage class to your GlusterFS

Private Image Repository
• Bundled Images
Import Docker images from bundle into private
registry, or import any Docker image you want to
deploy across your nodes.
• Secure Access
Add only the images you approve of so your
developers have trusted, validated images to build
from.
kubectl get serviceaccounts default -o json | jq
'del(.metadata.resourceVersion)' | jq
'setpath(["imagePullSecrets"];[{"name":"admin.registrykey"}])' |
kubectl replace serviceaccount default -f -
Command so all deploying pods can access private image repo

Network
Proxy, Calico, Internal and external
communication

49. IBM Confidential
Network Concepts
• Proxy Node
Transmits external request to the services
created inside your cluster.
• Calico Network
Enables networking and network policy in
Kubernetes clusters Learn more
• Network Policy
Labels specifying which groups of pods are
allowed to communicate with each other and
other network endpoints
• VMware NSX-T
Labels used in NSX-T can be mapped to
Network Policies in ICp for deeper VMware
control

50. IBM Confidential
VMware NSX-T Integration
IBM Cloud private will offer
NSX-T as the networking
mesh between pods on
VMWare ESXi 6.5

HA
How to run HA topology, workloads

54. IBM Confidential
IBM Cloud private highly available topology
Managementservices are running in all the master nodes.
• UI, kube-apiservice, docker registry (and so on) run in active/active mode
• Virtual IP manager assigns virtual IP to one of the master nodes to serve the UI/API
request
• Other services rely on etcd to select a leading instance (you could treat them as
active/passive mode)
• The number of master nodes should be odd (per request of etcd to handle split
brain issue)
• Proxy services are running in all the proxy nodes in active/active mode
• Virtual IP manager assigns virtual IP to one of the proxy nodes to serve application
requests. The number of proxy nodes could be any value.
