Easily migrate and modernize Linux and open source databases to Azure

Azure Migrate is your one-stop-shop in Azure for migrating and modernizing your virtual machines like Windows or Linux Servers, databases, data, web apps, and virtual desktops. Azure Migrate features free Azure migration tools with features like agentless datacenter discovery, Azure readiness analysis, cost estimation, app modernization, and app dependency visualization as well as popular migration tools from our ISV partners to help you in the discovery, assessment, and migration phases of your migration and modernization journey in one central location with end-to-end visibility.

In the below demo video, we migrated and modernized an open-source Java app, Airsonic, and its backend MySQL database, both running on-premises on Linux Virtual Machines, to Azure. To modernize the MySQL database, we moved the data from the on-premises virtual machine into Azure Database for MySQL, using the Azure Database Migration Service. Azure Database for MySQL is a managed database, so once you have the data in Azure Database for MySQL, you don’t have to worry about managing a virtual machine and you get the benefits of built-in scalability, high availability, enterprise-grade SLAs, and cost optimization.

For the modernizing the app, we containerized it using the Azure Migrate App Containerization tool, so you can achieve faster application development cycles, ease of deployment, and quick scalability offered by containers, all without making any code changes to the app. Also, check out this MySQL migration guide, to get detailed step-by-step guidance on how to migrate MySQL workloads to Azure Database for MySQL.

To learn more, watch the Microsoft Mechanics video below, which shows you step-by-step how to migrate and modernize your Linux and open source databases to Azure.

Get full support for Linux and high availability, industry-leading SLAs for open source databases

Azure supports all major Linux distributions including Red Hat, SUSE, Ubuntu, CentOS, Debian, Oracle Linux, and Flatcar Linux and open-source databases like MySQL, PostgreSQL, Cassandra, MariaDB, and more. More than 60 percent of Azure Marketplace solutions run on Linux. Then, beyond the workload level, Azure also contributes back to the upstream Linux and Kubernetes communities, that many of the modern and cloud-native architectures rely on.

Microsoft has done a ton of work for performance, reliability, manageability, and security to make Azure the best home for running any open source workload. Starting at the foundational level, Microsoft is working with the leading Linux Distros to optimize the kernels and hypervisors of Azure, including tuning the kernel for Azure hypervisors. Microsoft also works closely with Red Hat for managed services like Azure Red Hat OpenShift and SUSE with SAP enhancements. So when you bring your workloads to Azure, there is a benefit every step of the way, from onboarding to operation and you gain more security than you might have had on-premises, in your private cloud, or in another cloud. And whether you are starting greenfield or bringing what you already have running to Azure, we’ve got you covered.

Here is a summary of the key advantages of running Linux workloads and open source database services on Azure:

Support for all major Linux distros like Red Hat, SUSE, Ubuntu, Oracle Linux, Debian, CentOS, CoreOS, and OpenSUSE.
Azure-tuned kernels provide 25 percent faster network throughput.
Unique and integrated support experience. Our support teams work with Red Had and the SUSE support team, to triage your support cases together.
Minimal administration required for MySQL, PostgreSQL, and MariaDB with fully managed databases based on the latest community editions.
The best total cost of ownership, high availability, and built-in intelligence provided by managed databases.
Enterprise scalability with Hyperscale (Citus) which enables scaling of PostgreSQL across multiple servers and Query parallelization across those servers for faster responses.

Safety note: This is not a prescription or diagnosis. For severe symptoms, pregnancy danger signs, children with serious illness, chest pain, breathing difficulty, stroke-like weakness, or major injury, seek urgent care.

Which doctor may help?

Start with a registered doctor or the nearest qualified health center.

What to tell the doctor

Write when the problem started and how it changed.
Bring old prescriptions, investigation reports, and current medicines.
Write allergies, pregnancy status, diabetes, kidney/liver disease, and major past illnesses.
Bring one family member if the patient is weak, elderly, confused, or a child.

Questions to ask

What is the most likely cause of my symptoms?
Which danger signs mean I should go to hospital quickly?
Which tests are necessary now, and which can wait?
How should I take medicines safely and what side effects should I watch for?
When should I come for follow-up?

Tests to discuss

Vital signs: temperature, pulse, blood pressure, oxygen saturation
Basic physical examination by a clinician
CBC, urine test, blood sugar, or imaging only when clinically needed

Avoid these mistakes

Do not use antibiotics, steroid tablets/injections, or strong painkillers without proper medical advice.
Do not hide pregnancy, kidney disease, ulcer, allergy, or blood thinner use.
Do not delay emergency care when danger signs are present.

Medicine safety and first-aid guide

This section is for patient education only. It does not replace a doctor, pharmacist, or emergency care.

Safe first steps

Avoid heavy lifting, sudden bending, and prolonged bed rest.
Use comfortable posture and gentle movement as tolerated.
Discuss physiotherapy, X-ray, or MRI only when clinically needed.

OTC medicine safety

For mild back pain, pain-relief medicine may be discussed with a doctor or pharmacist.
Avoid repeated painkiller use if you have kidney disease, stomach ulcer, uncontrolled blood pressure, or are taking blood thinners.

Avoid these mistakes

Do not start antibiotics without a proper medical decision.
Do not use steroid tablets or injections casually for quick relief.
Do not delay emergency care because of home remedies.

Get urgent help if

Back pain with leg weakness, numbness around private area, loss of urine/stool control, fever, cancer history, or major injury needs urgent care.

Medicine names, dose, and timing must be decided by a qualified clinician or pharmacist after checking age, pregnancy, allergy, other diseases, and current medicines.

For rural patients and family caregivers

Patient health record and symptom diary

Write your symptoms, medicines already taken, test results, and questions before visiting a doctor. This note stays on your device unless you print or copy it.

Doctor to discuss: Doctor / qualified healthcare provider

Tests to discuss with doctor

Basic vital signs: temperature, pulse, blood pressure, oxygen level if needed
Relevant blood, urine, imaging, or specialist tests only after clinical assessment

Questions to ask

What is the most likely cause of my symptoms?
Which warning signs mean I should go to emergency care?
Which tests are really needed now?
Which medicines are safe for my age, pregnancy status, allergy, kidney/liver/stomach condition, and current medicines?

Emergency warning signs such as chest pain, severe breathing difficulty, sudden weakness, confusion, severe dehydration, major injury, or loss of bladder/bowel control need urgent medical care. Do not wait for online information.

Go to emergency care if you notice:

Severe or rapidly worsening symptoms
Breathing difficulty, chest pain, fainting, confusion, severe weakness, major injury, or severe dehydration

Doctor / service to discuss: Qualified healthcare provider; specialist depends on symptoms and examination.

Step 1
Check danger signs first

If danger signs are present, seek emergency care and do not wait for online information.
Step 2
Record the symptom story

Write when symptoms started, severity, medicines already taken, allergies, pregnancy status, and test results.
Step 3
Visit a qualified clinician

A doctor, nurse, or qualified healthcare provider can examine you and decide which tests or treatment are needed.
Step 4
Do only useful tests

Do tests after clinical assessment. Avoid unnecessary tests, random antibiotics, or repeated medicines without diagnosis.
Step 5
Follow up and return early if worse

If symptoms worsen, new warning signs appear, or treatment is not helping, return for review quickly.

Rural patient practical tips

Take a written symptom diary and all previous prescriptions/test reports.
Do not hide medicines already taken, even herbal or over-the-counter medicines.
Ask which warning signs mean urgent referral to hospital.

This roadmap is for education. A real diagnosis and treatment plan requires history, examination, and clinical judgment.
