Solution architect do I need to understand the code What knowledge and skills do you need to prepare for the solution architect examPosted by Coffey Duggan on February 13th, 2021 if you wish to be described as a solution architect, the first step you have to pass is always to pass relevant examinations to acquire professional certification, that may demonstrate that you have mastered some knowledge and will design complex systems. it's not easy to be a solution architect. To start with, you have to be an excellent engineer. Which means that you have an excellent knowledge of algorithms and learn how to apply them efficiently. Good developers also have to have experience in designing complex architecture systems. at present, typically the most popular certifications are AWS solution architect, azure solution architect and Google cloud platform architect. I'll guide you through the mandatory basics for preparing for the AWS Solution Architect exam, which also relates to other certification exams. computing power here is the basic pillar of cloud systems, regardless of the real physical server or the virtual environment behind the cloud system. What's important to us is a spot to perform the application form and the capability to handle the workload correctly. For that reason it is crucial to know the thought of configuring various kinds of computing systems. if the application form program consumes a lot of computing resources, the machine needs to have enough CPU and ram; if the application form program performs many I / O operations, the system has to focus on configuration. understanding the necessity for applications really helps to define system requirements. Like on Amazon, elastic cloud computing (EC2)It has numerous kinds of instances to generally meet different needs. Making a good choice may also save costs. ASG is a service in AWS. After the user base increases, scalability problems may possibly arise, that will be the thought of automatic scaling. If you will find not enough resources, it will automatically raise the number of calculators. When more and more machines begin to work, the flow ought to be evenly distributed included in this. Elastic load balancer (ELB) is yet another service in AWS, that may help you solve this issue. when the application really is easy, it could be transformed into no server, which means that the server and load balancer will not be configured, every thing will be handled by the cloud system, and it will scale automatically based on the traffic. A software can be quite a function or a chain of functions. The cloud system accounts for executing them, so it is named serverless. Amazon lambda is the service that performs these functions. storage there are many storage types available object storage, block storage or file system storage for different operating systems, which have their own purposes and applications. As a remedy architect, you have to be able to select the right solution to meet up what's needed to make certain good performance and make it cost-effective. · object storage (S3 in AWS) can be used for simple objects such as for example videos, pictures and documents. It has high data persistence and certainly will be used as a place to store application assets. · block storage（AWS (EBS) is a high performance memory with block level structure. This kind of storage can only just link to at least one computer at exactly the same time. But there is an alternative to split up it and put it to use down the road another computer. · file system storage (AWS EFS) offers a common structure between files and folders. This is useful for scenarios when sharing use of the info needed in the compute queue. It acts as a network driver and will be utilized by multiple users at the same time. database you need to have a clear knowledge of how a data in the database is organized. Before choosing a database, consider the following questions: · do you need to perform complex queries and dining table joins? · that will result in the maintenance and update of the database? database types include relational database and non relational database. Selecting the most appropriate database for the solution is important, which defines future performance and scalability. with relational databases, data can be more structured, which enables us to run various kinds of queries; non relational databases organize, save and query data in different ways (for example, as key value storage), making horizontal scaling better to execute. next, you need to select whether it is serverless or not. The serverless database is automatically maintained and expanded by the cloud system. Dynamodb of AWS is a non relational database without server, by which data is organized as key value storage. However , for relational databases, AWS provides services with different enginesRelational database services, Aurora and Aurora serverless (all Amazon proprietary databases). additionally , you have to remember just how many read and write operations to perform. Like if a great many other departments in the business are reading the database, you are able to consider using read copies; if you wish to see the same data multiple times, you are able to go for elasticache frequently cached requests. networking you must understand what public and private networks are. In distributed system, communication is organized through network. Using classless inter domain routing (CIDR) can restrict the usage of specific resources in the network, and it is also an essential area of the security solution. Of course, no one really wants to have public access to the database. In comparison, the database ought to be on a personal network and only allow inbound traffic from defined sources. set aside a second to understand the working principle of TCP / INTERNET PROTOCOL ADDRESS protocol and check different network topologies. This will reveal how to build a method with only just one Internet entry point, just how to only allow outbound traffic, and how exactly to protect against different attacks, and also have a stable elastic solution. Amazon features a rich pair of networking services. Listed below are just some of them: subnet, security group, virtual private cloud (VPC), Internet gate way, NAT gate way and web application firewall. this is actually the AWS Solution Architect examBasic knowledge required. Whether you are finding your way through any certification exam or want to further expand your knowledge, having the ability to build a flexible and scalable architecture is a very important skill. leave an email to like and pay attention to let's share the dry goods of AI learning and development if you wish to reprint, please leave a message in the background and follow the reprint specification please Black lapel blazer spo toLike it?
