Our strategy is built upon pillars that uniquely differentiate us in the market. We provide scalable, performant, secure and intelligent relational databases for: Born in the cloud applications and Existing applications which are either being modernized on-premises or moving to the cloud. Let’s walk through the pillars: Hybrid – we’re providing a frictionless migration experience for existing apps, whether moving to a fully-managed database as a service or transitioning over time with a hybrid strategy. Enterprise Scale and Performance – we’re helping customers manage their resources and build for the future with dynamic scaling up to 100TB. Security & Compliance – Security management can be complex, particularly when working across entire data estates. We are simplifying security with a consistent and comprehensive policy-based approach across the platform Built-in Intelligence – we’ve been enabling customers to be more productive and gather new insights with adaptive and ML-based features for a couple years now. We gather telemetry across millions of databases to fine tune our algorithms to do more and help our customers be more productive than ever. Choice - Our platform is under-girded by choice that guides customers to the right solution for their workloads at the best TCO. Customers can exercise choice and flexibility across the relational database platform, and be assured that they can maximize productivity, efficiency and ROI for any of their workloads. -------------------------------- Choice of hosting – on-premises, hybrid, VM or fully-managed PaaS Choice of engine – SQL, PostgreSQL, MySQL, Maria DB Choice of deployment options – instance and database scoped, compute and IO-intensive Choice of resources – wide spectrum of compute and storage Choice of languages - Python, Java, Node.js, PHP, Ruby, and .NET
- 지금부터는 1. 기능. 고가용성 및 비즈니스 지속성 성능 및 확장성 보안 및 관리 설명 2. 마이그레이션 방법 보여드리고 3. 사례 소개
- Azure Database for PostgreSQL의 고가용성 및 비즈니스 지속성
- 99.99% SLA 지원 Azure SQL DB와 마찬가지, Service Fabric 기반 기술 사용 복잡한 failover 구성, 비싼 고가용성 솔루션 없이 Azure Database Services is built upon the SQL Database platform which is a Service Fabric-based PaaS solution. As such, rather than having to boot-up an entire OS stack to bring up a new server (such as in IaaS), Azure Database Services run the database engine in a custom container technology which you can think of as a secure “pico process”. The time it takes to bring-up a new server in this custom container is a matter of seconds. This means that in the event that your database server has hung, or “gone away”, the Azure Database Management Service” detects the failure, brings-up a new server in this lightweight container, maps the new IP address to the DNS name of your instance and maps to your storage. This entire process takes between 30-45 seconds. This is built-in to all performance tiers of Azure Database Services and since a replica instance isn’t needed, there is no additional cost to the customers. In contrast, an AWS RDS server that is deployed in a single AZ would take minutes to start – and that does not account for how you would detect the failure and switch-over Scale compute up or down in seconds Scale storage instantaneously High availability without the need for replicas Setting-up high availability for database servers is hard, requiring either custom code to manage detection/failover, or expensive 3rd party solutions to make it a bit easier. Compute redundancy: If a node-level interruption occurs, the database server automatically creates a new node and attaches data storage to the new node. Any active connections are dropped and any inflight transactions are not committed. Data reliability: 3 copies of data for data reliability
- 오라클 -> 최대 95% 비용 절감 가능. 같은 Azure 내의 IaaS와 비교해서도 비용측면에서 장점 누릴 수 있음. 타 클라우드 벤더사 PaaS DB -> VM 형식 Customers who are IaaS customers in Azure today to understand that the specs of a VM do not equate directly to the specs of Azure Database Services. The reason is two-fold: Customers do not size a VM based on their typical workload, rather they size wisely to handle workload spikes so as not to impact performance of the application. With Azure Database Services, the ability to scale performance on the fly means they SHOULD size their instance based on typical workload needs and then elastically scale when necessary. This lowers costs. A VM has to support the performance requirements for both the database engine as well as the host OS. With Azure Database Services, the SQLPAL isolated pico-process (mini-OS) significantly lowers the HW needs compared to a VM. So in this example, if I have a D4S_V3 VM with 4 vCPUs and 32GB of SSD, when I choose an Azure Database for MySQL the customer can likely choose a smaller size of 2 vCores with the same storage (and in fact, they would get more storage as the storage for Azure Database Services is dedicated to the database, logs, etc. – no host OS footprint here). The customer can then profile their workload and determine if it meets their performance requirements, and if it does not, they can easily scale-up to the next tier. More importantly, in an IaaS VM implementation, if you want to achieve HA you need a second server (replica). This will double their costs, in this case from $143/mo. to $286/mo. With Azure Database Services with built-in HA, there are no additional replicas needed and as such – there is no cost impact. So to sum up this example, a HA IaaS MySQL VM costs $286/mo., whereas Azure Database for MySQL would cost $132/mo. That’s a saving of $154/mo.

- 추가 선택 옵션: 고급 위협 보호 감지 -> 관리자 알림 Azure PostgreSQL threat detection provides an additional layer of security intelligence which detects suspicious activities going on in the database. A simple way to enable threat detection using Azure portal, which requires no modifications to existing application code or client applications. A proprietary set of algorithms that work around the clock to learn, profile and detect suspicious databases activities, indicating a potentially harmful attempts to access or exploit data in the database. Someone has logged from an unusual location - change in the access pattern from an unusual geographical location An unfamiliar principal successfully logged- - change in the access pattern using an unusual SQL user. Someone is attempting to brute force SQL credentials abnormally high number of failed logins with different credentials. Someone has logged from a potentially harmful application It provides actionable alerts over email and in Azure portal which provides details of the suspicious activity and recommends how to further investigate and mitigate the threat. ---------------------------------------------------------- We are embedding machine learning directly into our cloud services to deliver intelligent data services that keep your data safe. For example, consider the security features in Azure SQL DB Our ML systems analyze and learn from over 700 TB data/per day to ensure we keep your applications highly efficient and data safe – through automatic auditing and threat detection. With active Threat Detection, the service can identify anomalies in your workload and alert you of a potential attack like SQL injection. The service does the hard work so you don’t have to – so you can focus on the business problems you’re solving and creating breakthrough applications. --------------------------------------------------------------------------------------------------- SQL Threat Detection allows you to detect suspicious activities indicating a possible malicious intent to access, breach or exploit data in the database. SQL Database Threat Detection runs multiple sets of algorithms which detect potential vulnerabilities and SQL injection attacks, as well as anomalous database access patterns (such as access from an unusual location or by an unfamiliar principal). Security officers or other designated administrators get email notification once a threat is detected on the database. Each notification provides details of the suspicious activity and recommends how to further investigate and mitigate the threat. “Azure SQL Database Threat Detection is now generally available Threat Detection leverages machine learning to provide an additional layer of security built into the SQL Database service, enabling SQL Database customers to protect their databases within minutes without needing to be an expert in database security. It works around the clock to profile and alert you of anomalous activities on your databases. Threat detection alerts can be viewed from Azure Security Center and provide details of suspicious activity and recommend action on how to investigate and mitigate the threat.
