Best time to plan to migrate your on-premise datacenter to Azure

, , , , , , ,

Everybody’s at home and tries to find an interesting topic and goal to spend the time useful. Or feels exhausted? Therefore you need to find a exciting activity or area where you can do some relaxing in the world of technology. Today I would like to suggest a great topic which is both exciting and useful. 2in1! It’s cool, isn’t it?

After the first quarter of 2020 you could read in financial reports: the On-Premise related revenues is higher than cloud related ones. Why? Maybe, during the current situation most of companies decreased their cloud related activities. Nevertheless this is not the best strategy in long term. I would not like to make financial analysis now, merely draw your attention, this is a great chance to plan and test “How you can on-premise datacenter to Azure”. And here there is another big “why?”.

Now the time pressure is lower, the workload is far from the usual. Additionally you may feel you don’t have huge motivation for your everyday activities. No problem, let’s start to do some exciting, something new, or something which is waiting for you… 🙂 The migration planning and playing with migration is one of the best activities for this purpose.

Azure has a prominent part that supports the migration of external resources (such as on-site) to Azure. This is the Azure Migrate. With this you have chance to migrate your on-premise services to Azure on a partial managed way.

You can migrate tons of resources like:

  • Windows and Linux servers from Hyper-V
  • Windows and Linux serves from VMWare
  • Windows and Linux Physical servers
  • Databases
    • MS SQL
    • MySQL
    • MariaDB
    • Non-SQL
  • Web Applications
  • VDIs

To start, I suggest to start the read the documentation above. Nevertheless, if you just would like to jump into the middle of this topic, let’s start on Portal. In Azure Portal, when you open Azure Migrate service page, you can realize this is a well structured and understandable process. Please don’t forget the migration is never an easy (next-next-finish) process.

I wouldn’t like to create a step-by-step action plan for each and every resource type migration because that is impossible. Sorry for this bad news. Nevertheless I would like to share some useful links to migration. These links could help you to do your best to discover the resources which could be migrated then you can plan the migration (in time and steps).

Maybe you know, the “Lift and Shift” migration strategy is not the best solution for long term. Additionally there will be several services which cannot be migrated without re-development, rebuilding, restructuring. Here you should think about microservices. Then you should choose the right architecture pattern. You should “choose” one of from XaaS (IaaS, PaaS, SaaS, etc.). As you can see this is very-very complex topic. However this is a great chance to improve your knowledge and spend your time usefully.

Finally, here are the links for you:

… and millions like these on the internet. 🙂

I hope this article helps you to feel better in this period. And it supports your professional improvement.

Post-Easter News bouquet

, , , , , , , , , ,

I hope you spent well the Easter holiday and you had enough time for relaxing.

Luckily I feel good and the last week was really great. Therefore I would like to give you a post-Easter news bucket in this week. 🙂

1. Action required: Azure Database

Maybe you also received an email with this subject. If not, you should know, Microsoft is going to change the public endpoint IP of MySQL, PostgreSQL Single server, and MariaDB in more regions.

Change time window: 20 May 2020 00:00 UTC – 30 June 2020 00:00 UTC.

Recommended action:

  • Ensure the firewall allows outbound traffic on port 3306 for MySQL/MariaDB and port 5432 for PostgreSQL to the new IP address(es).
  • Connect to your Azure Database for MySQL, PostgreSQL Single server, and MariaDB using the DNS record instead of the IP address.

2. Temporarily halted any deprecation enforcement of TLS 1.0 and 1.1

Since 2018 we know the TLS 1.0 and 1.1 will be deprecated in 2020. Nevertheless, due to the known reason, Microsoft postpone this until middle of summer.

Some articles in this topic:

3. Azure Monitor for virtual machines is now generally available

Yesterday, Microsoft updated their earlier announcement about Azure Monitoring for VMs. To be honest, I was very happy about the original announcement because I already liked this feature in preview.

You can find more information here: Azure Monitor for virtual machines is now generally available

4. Azure Monitor Logs new create workspace experience

My other favorite area regarding Azure Monitoring is Azure Monitor Logs. Some days before Easter informed us about Azure Monitor Logs new create workspace experience.

As they say:

The workspace creation experience has been modernized and there’s a new, full-screen create experience.

Azure Monitor Logs new create workspace experience

Is it better or not? What do you think? 🙂

5. Logic Apps improvement

Finally, a small but good news. Microsoft continues the improvement of Logic Apps for better usage and better automation. They started that in last November: Workflow automation with Logic Apps. And now they provided the actual progress. You can find the new announcement here: Workflow automation with Logic Apps

Have a great spring and take care. 🙂

ppdiag_elasticache_redis_caching

Global Datastore for Redis in AWS

, , , , , , ,

When you start your business and you have only a few Customers you are in an easy situation from performance perspective. I mean, you should provide some resources to your Customers for the right and acceptable performance.

Then your business is growing, you must serve your customers need, and increase system performance. Sometimes this is easy, sometimes not.

For this there is a quite common solution which helps you to provide a fast and reliable service. This is the Redis Cache which is available for almost every solutions in the cloud.

Redis is a great solution. You can find more information for the bigest hyperscalers’ offer:

All of them are great, reliable, easy to use and fast. Nevertheless Today I would like to draw your attention for a brand new feature which allows you to replicate your Redis Cache data among different regions. Is it cool, isn’t it?

I am sure you know the AWS ElasticCache for Redis

AWS ElasticCache for Redis

From now AWS offers cross-region replication for this cache service.

How it helps?

This solution could be useful if the geolocal performance is important for you, or from disaster recovery point of view.

How it works?

  1. When you have an existing Redis cluster (or you build a new one) somewhere the Global Datastores are supported. This will be the primary (active)
  2. After some configuration steps AWS provisions the secondary (passive) Redis clusters to the selected regions. (You can create maximum 2 passive clusters)
Replication Across AWS Regions Using Global Datastore

Limitations

As you can see above there are several limitation of this feature.

  • You only can add READ caches for your primary cluster
  • Maximum number of replicas: 2
  • Global Datastore is available only some regions
  • ElastiCache doesn’t support autofailover from one AWS Region to another.

The full list of limitations you can find here: Prerequisites and Limitations

Finally you can find the detailed information AWS Documentation page: Replication Across AWS Regions Using Global Datastore

If you feel this could be a great opportunity to increase your business performance in the near future. My suggestion to start to discover this new feature.

We got some time from Microsoft

, , , , , , ,

Maybe you remember I published an article about the future of Microsoft certification. As you read: 2020 is year of the changes: Microsoft Azure Certification. Accordingly everyone started to reorganize their plans regarding the trainings and exams for this year.

Then last week Microsoft announced several significant changes which affect everything we planned since beginning of February.

I can see tons of question marks in your mind. Is it good news? Is it bad news? Let me quote something:

Ah, Shifu, there is just news. There is no good or bad.

Oogway (Kung Fu Panda)

So, don’t worry…Microsoft announced the following thins:

  • Testing centers closing and online proctoring capacity increasing
  • Reschedule and cancellation fees waived
  • Retirement of MCSA, MCSD, MCSE certifications and related exams extended
  • Expiring role-based certifications extended
  • Exam voucher and discount offer expiration dates extended
  • Moving to virtual training

In nutshell: Microsoft increases its online exams related capacity which is really good news. Additionally if you have any expiring certification, voucher or discount offer, it will be extended until January 31, 2021. Finally, all MCSE, MCSA, MCSD certification retirement date is postponed to January 31, 2021.

For the details, you can read the whole article here: An Important Update on Microsoft Training and Certification

Luckily, last week I provided a post to you about the possibilities of Azure Online Exams. According our current information, Microsoft has enough capacity to manage our ambitions regarding online exams.

So Let’s go back and start to plan our career path again. 😉

  6. Enter your phone number
  7. Then you can start the check in process
  8. Click on “Get started” button
  9. In this screen your webcam, microphone and internet will be tested
  10. Then click on Next and continue with verification photo step. (I have chosen the url)
  11. Follow the instructions on your phone
  12. On your phone you have to provide sever photos for your identification:
    1. Your picture
    2. Driving license or Password
    3. Work-space (here you must provide 4 photos from different angle)
  13. After you click on Refresh button and you are done. 🙂

Please, don’t forget, you have to do it again when you will start the real exam.

Step 3 – schedule the exam

Final step to schedule an exam. You can do on Browse Microsoft Certification exams page on Microsoft Learning.

I hope this help you to be more motivated for get Azure Certificates.

Now you can take exams from home. Good luck for the exams. 🙂

VSO

Visual Studio Online: New features

, , , , , , , , ,

Last November Microsoft announced the Visual Studio Online Public Preview. “Visual Studio Online provides cloud-powered development environments for any activity” as Microsoft defines. This is a really great idea which requires an active Azure Subscription. Additionally you can manage your VSO environments from Visual Studio Code.

This was in last year. And now Microsoft provides some new updates to us such as Dockerfile support. Then the Real-time Collaborative Development is far stable than before.

I really like this feature because it could be useful for collaborative development and/or debugging. You can share your thoughts with your colleagues, during all of you can see the code in live.

Long story short, you can find the details in What’s New in Visual Studio Online article.

I suggest to try the new way of development, because it’s cool. 🙂

AzureCognitiveSearch

Changes: Azure Cognitive Search is the new name

, , , , , , , , , 0

As usual – and luckily – there are some changes in Azure day by day. My opinion is: this is right the way of improvements on every area of the world. Nevertheless most of cases we are facing with price related changes, which are not the most enjoyable for us and our business.

In this case there is “only” a name changes where the Azure Search is renamed to Azure Cognitive Search. This change is going to be (effective) applied on 1st February 2020.

Don’t worry about this change because (as i mentioned above) it won’t impact the pricing of the service. Nevertheless please be careful regarding your billing procedure regarding this service. Why? Because from 1st February this service belongs to Cognitive services. This means the name change causes a service type related change. It’s not a big deal, merely please be careful and well-prepared for this. 🙂

Finally, please find the following table which contains the related name changes:

Stephane Eyskens has been working on brilliant Azure maps for months, then he shares them with us…and I share them with you. 🙂

Now he made a merged Azure Maps where you can find all Azure maps together:

As usual, you can also find this merged map on Mindmap Maker.

I hope you could use it for your personal or professional level. 🙂

AKS Architecture Map

, , , , , , ,

Welcome in 2020…the year of tech jungle. 🙂

As you remember I posted several articles where you could find great maps for Azure services.

Today I would like to share with you the The AKS Architecture Map from Stephane Eyskens (@stephaneey). As usual this map is available on Azure Developer Community Blog and on Mindmap Maker as well.

As you can see this map focuses on several important area such as Network, Scaling, Storage, Monitoring, Deployment, etc. This means it is very complex to read and find the relevant in formation you are you looking for. Therefore the author made some explanation (behind the attachment icon) and external links (behind the link icon) for the better understanding.

As you can see in Stephane’s article there will be several another interesting maps for Azure. Next time I will provide them.

Thank you Stephane this great XMAS gift.

Elasticsearch: Install ingest node

, , , , , ,

In this summer I started to work with ELK stack on Azure. This is another interesting topic if you want to increase efficiency of your DevOps activities.

As usual I started with Elasticsearch:

The open source, distributed, RESTful, JSON-based search engine. Easy to use, scalable and flexible, it earned hyper-popularity among users and a company formed around it, you know, for search.

elastic.co

Long story short, I decided to create some hands-on video to show you how you can install and configure an Elasticsearch cluster step-by-step.

First part is: Step-by-step installation and configuration of Elasticsearch 7.3.1 ingest node to Ubuntu 18.04

You can find the related commands here:

# Execute as root
sudo -i

# Get Linux version
cat /etc/issue.net

# Install java
apt install openjdk-8-jre-headless -y

# Check java version
java -version

# Start installation
wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -
sudo apt-get install apt-transport-https
echo "deb https://artifacts.elastic.co/packages/7.x/apt stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-7.x.list
sudo apt-get update && sudo apt-get install elasticsearch

# Install vim
apt install vim -y

# Change vm settings - vm.max_map_count
sysctl -w vm.max_map_count=262144

# Edit configuration
vim /etc/elasticsearch/elasticsearch.yml

cluster.name: my-search
node.name: ${HOSTNAME}


## Add - Client
### Turn off data functionality
node.data: false
### Turn on ingest (client) functionality
####### before 5.0
####### node.client: true
####### 5.0 or later 
node.ingest: true


# System configuration
vim /etc/security/limits.conf

*       soft    nofile  64000
*       hard    nofile  64000
root    soft    nofile  64000
root    hard    nofile  64000

vim /etc/pam.d/common-session
session required                        pam_limits.so

vim /etc/pam.d/common-session-noninteractive
session required                        pam_limits.so

# Check MMAP settings
ulimit -m


# HEAP SIZE: RAM/2 = HEAP
free -m

vim /etc/environment
ES_HEAP_SIZE="2g"

# Start elasticsearch cluster
service elasticsearch start
systemctl enable elasticsearch 
### sudo update-rc.d elasticsearch defaults 95 10
service elasticsearch status

curl http://localhost:9200

#### !!!!! REBOOT vm !!!!! ####

It is easy! 🙂

Security Architect Map for Azure Services

, , , ,

End of June this year I posted an article with a great stuff regarding Azure. In this post (Solution Architect Map for Azure services) you can find a brilliant diagram which helps you or other Architects finding the “right way in Azure”.

Today I would like to share with you the Azure Security Architect Map from Stephane Eyskens (@stephaneey). As usual this map is available on Azure Developer Community Blog and on Mindmap Maker as well.

As you can see this map focuses on several important area such as Network Layer, Identity Layer, Security Posture, etc. This means it is very complex to read and find the relevant in formation you are you looking for. Therefore the author made some explanation (behind the attachment icon) and external links (behind the link icon) for the better understanding.

As you can see in Stephane’s article there will be several another interesting maps for Azure. Next time I will provide them.

Thank you Stephane. It is brilliant work.
