This post is part of Q/A series of Module II Oracle Cloud Offerings from Day 2 (on 3rd Feb 2018) DBA to Cloud DBA Live Training asked by trainees. These questions will help you to understand Cloud Services and also if you have any question related to Oracle Cloud or Cloud DBA then you can ask in the comments section.
For Q/A of DBA to Cloud DBA Day 1 Training from Module I, refer to https://k21academy.com/cloud22
If you are just starting out in Cloud then I highly recommend you to go through these first
- Cloud for Beginners (Facebook Live): SaaS | PaaS | IaaS and which one is right for DBAs
- 12 Point Checklist for DBA for Beginner to Expert Cloud DBA (Facebook Live)
- If you are confused to pick Amazon AWS or Oracle Cloud then check this
- To check tasks performed by DBAs in Cloud here
Q1: First question comes from above slide, Is there any legal document signed between the cloud provider and the customer related to security? Who is responsible for Data Leaks/Data Theft in Cloud, Cloud Vendor like Oracle / AWS or Client?
A1: Yes, Legal document signed between client & cloud vendor like Oracle or Amazon, when you register for Cloud Account as well as when you opt for a specific cloud service. This contract/agreement is signed online at the time of Service Registration. Related to Responsibility for Data Theft/Leak, it depends on
- Service Model (SaaS, PaaS, IaaS check more at https://k21academy.com/cloudlive01 )
- Deployment Model (Public, Private, Hybrid, Managed to check more at https://k21academy.com/cloudlive02 )
- Also on How Leak/Theft happened (If Any)
All top cloud vendors like Oracle, Microsoft, Amazon, Google, IBM etc take security very seriously and provide options to encrypt data at rest, transit (over network) including Firewalls & Virtual Private Networks (VPNs)
Q2: Is there a doc or link to see which data centre to choose for each country?
A2: This is covered in our Activity Guide (For list of Activity Guides we cover in DBA to Cloud DBA training, check https://k21academy.com/cloud05 )
You can also get it from https://cloud.oracle.com/data-regions (Green represents what’s available as of Feb 2018 and Orange represents, what’s coming)
Q3: Can we create more than one FREE Trial account on Oracle Cloud?
A3: No, for the same Identity (Email & Phone Number), however, you can create another FREE Trial Account on Oracle Cloud using a different email and phone number.
Next question is from Module I recording on our Membership Portal. For our training, we provide videos in form of lessons, and related lessons are combined in a Module. We encourage attendees to watch these before coming to live interactive session to make the live session more interactive.
This also helps those who want to revisit a particular topic again or wish to learn their own pace or don’t have time to attend the live interactive session.
Q4: I just joined this DBA to Cloud DBA Training Course https://k21academy.com/cloud03. I watched the recorded video of Module I, What is chargeback in one of the videos you mentioned?
A4: Chargeback is a mechanism by which you as IT department managing Cloud (or offering Cloud as Service) can charge different departments within your organizations using Cloud Services.
Q5: What is Orchestration? Can you please elaborate?
A5: Orchestration in the context of Cloud, lets you schedule & track workflows that execute scripts on a host or invoke web service endpoint from a single location.
Example would be when a Cloud DBA creates a database on Cloud, process will ask set of questions and based on that
- Provision a Virtual Machine with selected CPU, Disk, RAM
- Install Database Software
- Start Virtual Machine & Databases Services
- Notifies Users about database creation
For IaaS i.e. Oracle Cloud Infrastructure (OCI) or OCI Classic, there is Orchestration V1 and more simplified V2 and you can see Comparison between V1 & V2 here
In Oracle Cloud Offerings Module of Training, we cover Oracle SaaS, PaaS and IaaS Offerings and few questions were around Performance Management, Application Management & Orchestration
Q6: Do we need to choose orchestration if we want it or it is included in PaaS?
A6: Some basic orchestration and one specific to database, i.e. compute for DBCS/DBaaS is already part of PaaS but if you want more advanced Orchestration and for tasks that are not part of DBCS then you can go for Orchestration Cloud Service, more at https://cloud.oracle.com/en_US/orchestration
Q7: Who is responsible to look at Performance Issues in Cloud, Cloud Vendor or Customer?
A7: Like security (discussed in Q1), performance depended on Service Model you are using. If this is DBCS/DBaaS or any application on PaaS, the customer is responsible for performance on PaaS or IaaS as Customer manages How much CPU & Memory (including JVM for WebLogic or SGA/PGA for Database) or what type to Disk to provision when provisioning Cloud.
So in PaaS or IaaS, it is the responsibility of a Customer where for SaaS, Cloud Vendor is responsible for performance.
Q8: Management Service like Application Performance Management (APM) or Log Analytics, Does it have a separate license?
A8: Yes these are additional services apart from DBCS and you pay for using these additional Management services.
Q9: Can APM, Log Analytics & Infrastructure Management, monitor on-premise servers including performance?
A9: Yes this is possible and if you already have OEM 12c/13c on-premise then you connect that with Cloud Service. If you don’t have OEM 12c/13c on-premise then you deploy a lightweight Java Agent and manage/monitor using APM, Log Analytics & Infrastructure Management Cloud Service.
Oracle has rich set of PaaS offerings and on Day 2 we covered Module II i.e. Oracle Cloud Offerings includingJava Cloud Service (JCS) that includes WebLogic Server, Coherence & Oracle Traffic Director (OTD i.e. Software Load Balancer & Web Tier)
Q10: Can you give some example what to host on JCS?
A10: JCS will be used for any application running on WebLogic like any J2EE Application. This is mainly for a client who has standalone Java Application or any application that runs on Weblogic and if you wish to move these to Cloud then similar to DBCS/DBaaS to run Database on Cloud, you have JCS to run WebLogic on Cloud.
Note: Apart from JCS, you also get JCS SaaS Extension more at https://cloud.oracle.com/java
Q11: Where does E-Business Suite (EBS) R12 or Peoplesoft come, SaaS or PaaS or IaaS?
A11: EBS can be deployed on A) IaaS Only or B) IaaS with PaaS (DBCS for Database Tier). More on Deploying EBS (R12) on Cloud on Cloud an Architect’s perspective then check Live at https://k21academy.com/cloudlive04
Note: There is also ERP on Cloud that is a SaaS solution based on Oracle Fusion applications, more at https://cloud.oracle.com/erp-cloud
Q12: How different is IDCS with OAM/OID?
A12: IDCS stands for Identity Cloud Service whereas OAM/OID is on-premise SSO/LDAP solution. In IDCS, you manage users, groups, roles, applications and manage Identity on Cloud. More on IDCS is at https://cloud.oracle.com/en_US/identity/features
Q13: If EBS (R12) on-premise is integrated with OAM/OID on-premise. If this EBS in-migrated to Cloud, How do we do the SSO?
A13: You can use EBS Cloud Admin Tool https://k21academy.com/ebscloud11 to integrate. We cover EBS and OAM/OID integration in our EBS on Cloud Training for Apps DBA’s at https://k21academy.com/ebscloud05
Oracle is also working on integration with IDCS (not yet certified as of Feb 2018) using CloudGate. Check IDCS OAuth support in white paper here
Stay tuned for next session next week where we’ll cover Oracle Database Cloud Service (DBCS & DBaaS), and How to Create Database on Oracle Cloud.
