What is On-Premises, IaaS, PaaS, SaaS and IaC?

By inAmazon, AWS, DevOps, Microsoft, Microsoft Azure, Powershell, VMware, vSphere Tag , , , , , , , ,
  • Infrastructure as a Service (IaaS)
  • Platform as a Service (PaaS)
  • Software as a Service (SaaS)
  • On-Premise
  • Infrastructure as Code (IaC)

Examples I’ve used

What are the differences?

Infrastructure as Code

So what is IaC, Infrastructure as Code? Standardise Infrastructure, Automate deployment and recreate, well-documented code. Exampled formats such as JSON & ARM templates.

DevOps teams will use IaC to recreate production like environments in dev cycles. Validate and Test deployments, prior to a production deployment. The end result being able to deliver a stable and repeatable environment.

Azure Resource Manager

The alternative to just running scripts. Manage your infrastructure resources in a group by templates. In addition, you apply security (RBAC) and tags, then associate costs to the group.

OMS – Azure Automation

By inMicrosoft, Microsoft Azure Tag , , , ,

What is OMS? .
Is it.. System Center Online rebranded?
OMS is used to gather logs centrally and make decisions upon this information.

What can you do with Operations Management Suite (OMS)?
PaaS application which is running on Azure
Use it to manage on prem or azure based VMs

How do you create and OMS setup
Ideal concept, Log all the information to a storage account. OMS will trawl the logs to make use of the information. The default agent in a VM has the information to transfer to a storage account and passing it to OMS.

Grab solutions from a portal.

  • Check status of patches
  • Change management
  • Log queries
  • Identify weakness in the environment

How you access OMS
OMS workspace is accessed via a web browser to view the information.

OMS Pricing
OMS free version holds data for upto 7 days
OMS costs for per machine monitoring

Identify Weakness or Issues.
For example No End Point security on VMs might be flagged
A recommendation to install a 3rd party tool.
Example : Deep Security – Trend Micro. An Azure recommended product for end point protection appears on the list in the filtered market place

Microsoft Azure PaaS – Web Apps, Storage and Site Recovery

By inMicrosoft, Microsoft Azure Tag , , , ,

PaaS / App Service

Check out the Azure App Service gallery of applications

Most Web Apps would use Autoscaling

When deploying web apps, consider integration and deployment options.. GitHub, DropBox, Visual Studio etc

Additional features include Azure WebJobs or Functions (functions for background tasks)

How you connect to the web apps could be a hybrid connection or VPN

Azure virtual network is available for the web apps ( standard upwards)

Authentication and Authorization ( Azure AD is optional, but there are easy connections to Facebook, Amazon, Google etc )

 

Mobile Services to Mobile apps

Logic APP

Work flow is built in to Office 365

If you get twiter post… Send mail. Etc flow

 

Traffic Manager

Traffic Manager has a cost (multi region coverage)

Load-Balancing single sites (free)

 

Storage

Planning and Implementing storage, backup and recovery methods

Blob storage, Table storage, Queue storage, or File Storage

 

Content Delivery Network

Videos / Office 365 back end Skype Business runs on it to handle to mass meetings, converting the presenters meeting to MP4 video and distribute via CDNs

CDNs cached copies in multi regions

1st connection costs

2nd onwards uses the cached copy

 

Backups

Use your own method, Use Azure backup, backup on prem, backup in the Azure

All done via DPM

Backing up VMs in Azure is fast. Incremental is the option and then its one option to do a full restore of a VM

DPM will dedupe the OS section of the VM in Azure, Hyper-V and vSphere VMs

 

Azure Site Recovery

Orchestration, replication and failover.

Switched off replica server in IaaS

Replicate , VMware VMs, Physical, Hyper-V VMs, Hyper-V hosts

Documentation on the setup of VMware VMs to Azure using Azure Site Recovery

https://docs.microsoft.com/en-us/azure/site-recovery/site-recovery-setup-replication-settings-vmware

Site Recovery concept to migrate to Azure

Implementing Microsoft Azure Infrastructure Solutions – Overview

By inMicrosoft, Microsoft Azure Tag , , , , , ,

Azure – What are the options?

IaaS, PaaS & SaaS

IaaS – Virtual Servers in the Cloud.
Easiest/ Logical method of moving to the cloud is IaaS. Drag your on prem Virtual Machines in the cloud. Basically transferring your on prem virtual machines in to the Cloud (Azure).
In event of failure on prem option, to run in azure, or migrate to azure
Active Directory – Azure AD connect. In a Hybrid environment

PaaS – Azure App Service
Storage, back and recovery services
More advanced – AI – Audio to Text PaaS

SaaS
Complete Software solution

What is the exam?
Exam : 70-533 Implementing Microsoft Azure Infrastructure Solutions.
Expect 1-4 questions are PowerShell based

In theory, you will need another exam to qualify for the certification MCSE Cloud

Why move to Azure?
DR solutions
Hybrid options
Cost saving option – Turning off services over night will massively save money IaaS.
Auto scaling
Pay As You Go : Azure for your dev environment
SaaS

Location knowledge
Note : Geographic areas and some cost more to host and some have limited features.

West Europe would appear to be the best option for local businesses in Sunderland (UK).

But – Check features are available in a region.

Documentation
Location to learn information https://docs.microsoft.com/en-us/azure/

DevOPS : How to deploy to Azure . https://docs.microsoft.com/en-gb/vsts/deploy-azure/

Market Place : Search for products available on Azure

Azure Services / Categories
Compute, Networking, Data and Storage, Web & Mobile, Other services include AD, automation, logging, monitoring

Azure Portals
https://Portal.azure.com
Or old world
https://account.azure.com

Deployment methodologies
Visual studio or visual studio code (free option)
Resource templates. Json files

Log Analytics and ( Operations Management Suite )
Centralised location for gathering log information
Patch management view
Change management view
Resource monitoring

Thought : Could this be described as a new version of System Center, SCOM, WSUS, but a cloud version?

Azure Virtual Networks
Choose the IP address spaces. Don’t use a subnet where you might duplicate your on prem servers.
Azure utilises some IPs .. So smallest subnet /29 subnet

Azure Load Balancer – Overview
Internal, Internet, Application Gateway, Traffic manager
SSL offload & WAF

Azure DNS
PaaS DNS is quite limited or Create a VM hosting VMs for internal DNS / Domain Controller.

Template Examples
Github.com/Azure-quickstart-templates
Deploy to azure ( for speed, test it out at your own risk )
