The engineer talked realistically!The importance of "multi -cloud skills"

　Oracle Nippon Oracle held the first Oracle Cloud conference event "Modern Cloud Day Tokyo" on August 6 and 7, 2019.

　On the second day of this event, "Oracle Cloud Infrastructure" as a site engineer who has been using various public clouds such as Amazon Web Services (AWS) with Nobuya Omori of System Intectrator and Bluememe Uehara.A session was held to talk about how (OCI) is evaluated and what expectations are expected in the multi -cloud era in the future.

　In the second half, there was a question time from the venue, and we talked about the “multi -cloud skills” that cloud engineers should wear in the future.In addition, the establishment of the user -led OCI user group is also announced and exciting, reported on this session.

Mr. Uehara (Chuo Left) and Nobuya Omori of Atomitech Cloudii (Chuo Right) are the Bluememe Professional Service Department, and Nobuya Omori (Chuo Right) of the Bluememe Professional Service Department.The moderator was Nippon Oracle Taku Sugiyama (left end) and Ryota Kato (right end).

Atomitech: "The price was cheap" OCI, Japanese user group started

　Atmitech offers a cloud service "Cloudii", a cloud service that supports all -round technologies from the introduction of OCIs, the migration of existing systems, and operation and maintenance in client companies.Since August, Cloudii users have also started to provide the "Cloudii Cloud Manager" management tool for multi -cloud environments that can centrally manage IAAS such as OCI and AWS and Microsoft Azure.

　Omori, an infrastructure engineer, has been using AWS, including participating in JAWS-UG Aizu as a core member.And about a year ago, I started touching OCIs, and most of the tasks are now using OCI.By the way, Omori's favorite service is the "Oracle Autonomous Database" series, which can easily build, set and operate databases.

Atomitech Omori."Recently, when I went to Jaws-UG, some people came to say," Ah, an Oracle Cloud person has come. "

　Omori started using the OCI because Atomitech decided to launch the Cloudii service in anticipation of the opening of the OCI Tokyo Region.

　"To be honest, when I was invited by my boss to use OCI, I thought," Oh, why Oracle!? "I thought that the strategy was interesting, and I thought it would be a new experience for myself, so I decided to challenge "(Mr. Omori)

　After the release of Cloudii in October 2018, Omori laughed, saying, "I have time to carefully verify the OCI and accumulate knowledge," he laughed, saying, "The Tokyo Region was difficult to open."He said that since the Tokyo Region was launched in May, Cloudii's acquisition projects have been increasing steadily as the initial aimed."There are many cloud migration of systems using Oracle Database," said Omori.

　The impression of the first time I touched the OCI was "Screen operation seems to be easy for beginners."It was also good that the official document was in place and the tutorial was useful.On the other hand, at present, it is also true that "IAAS service lineup is less" than AWS and others.However, he said that this was similar to when Omori began touching AWS, and that OCI was gradually increasing the speed of addition / update.

　"The most nice point as an infrastructure engineer," Omori cited the cost of use, especially the network service, was very low.For example, the “OCI FastConnect”, a direct connection service between the on -premises environment and the OCI, is a fixed fee type on an hourly basis, and there is no charge for the data transfer amount.In fact, when compared with the connection service of other companies' clouds, he said, "The price was cheap. I think it's especially good when configuring a hybrid cloud."

OCI's first impression and expectations for the future.He said that the opening of the Osaka Region in 2019, "I'm looking forward to making customers a new proposal again."

　Omori also announced that the OCI user group "OCIJP" was launched.We will share know -how and exchange opinions, including those who are already using OCIs and those who want to touch them in the future.The first event will be held in Tokyo on September 17.

Bluememe: Transferred multiple internal systems on the OCI and realize technical strengths

　Next, Mr. Uehara, a Bluememe infrastructure engineer, was on stage.

　Bluememe, which is a system integration and software sales specialized in large -scale agile development / model -driven development, uses OCI as a service provision base for Agile SDK using the ultra -high -speed development base "Outsystems". ing.

　This time, Mr. Uehara introduced a case where Bluememe adopted the OCI as a multiple internal system base.In recent years, the company has expanded its organizations and bases with the rapid expansion of business.As a result, the network configuration between the base / base has become more complicated, but the number of network engineers that can be in charge is short, and we want to reduce the trouble of operation management as much as possible.So we decided to migrate the internal system in the on -premises in the cloud."At that time, the president met the Oracle Cloud sales representative, and this project was going to go with OCI," said Uehara.

Bluememe Uehara."OCI has few services, but it may be rather good for new employees. I think it is easy to follow information because the service will increase in the future."

　Specifically, we worked on the IP-PBX server for extension IP-PBX servers, migrating in-house VPN servers, and migration to the sales management system that used Oracle Database to Oracle Autonomous DataBase (currently on progress).

　First of all, on the IP-PBX server for extension telephone, you can access (without VPN) via the Internet by shifting to the OCI to a form that connects to an on-premises server via the outside (outing) or a VPN.I did it.As a result, it has been changed to an environment that can respond even if the number of bases increased in the future."It took less than a month to migrate the cloud. From this experience, I thought," Isn't the OCI a surprisingly usable? "

　In the cloud migration of the VPN server, the VPN server and the RADIUS authentication server were placed on the OCI.What helped here was the "VCN Transit Routing" function (VCN: Virtual Cloud Network).There are both internal system servers that have migrated on the OCI and those left in on -premises, but if the user accesses from outside the company, if you connect to the VPN router on the OCI, VCN Transit according to the access destination server.The routing function was able to make a hub and spoke -type network.

　"I felt that this VCN Transit Routing function was able to be used better than other clouds. By preparing this environment with OCI, even if the number of bases increased, a new VPN with the headquarters is built.You no longer need to do "(Mr. Uehara)

In Bluememe, the VPN server cloud migration has been completed using OCI.Currently, Autonomous Database of the sales pipe system is underway.

　In terms of security, he felt the strength of "Enterprise cloud" in some respects.In the OCI, the OS firewall on the instance is provided in a set state from the beginning, preventing security risks due to omissions.In addition, it has a state -full -integrated firewall, and the network ACL (access control list) is a state full, so that the entire segment administrator and each instance administrator, each of which is set to be "double protected".explained.

　Like Omori, Uehara also appreciates the cost performance of OCI.In particular, the server instance using AMD EPYC processors is "surprisingly cheap, so I wonder if this is okay."On the other hand, he commented that he felt that the OCI's service lineup was still small and expected to expand the service in the future.

"Multi -cloud recommendation" for future cloud engineers

　In the latter half of the session, the audience at the venue posted questions from smartphones in real time, and a corner was set up by Omori and Uehara.It was a short time, but more than 40 questions gathered, and about 10 questions were answered.

　Questions from the venue were often compared to other companies' cloud services, especially AWS cloud services.For example, when asked, "Is AWS and OCI the way of building an environment very different?" Both of them have OCI's unique functions and ideas, but the basic concept of instances and networks is not very different.He replied that if he had touched AWS, he would be able to enter the OCI smoothly.

　In response to the question, "Is there a service in the OCI that can easily achieve containers and serverless architectures like other companies' clouds?"He introduced that there are services such as "Oracle Functions", which provides an open source serverless environment, and explained that "cloud native services are also steadily added."

　The question was asked, "What are the advantages that Enterprise is not the continuation of on -premises, but to the OCI?"Mr. Omori explains, "How can we make use of the merits of the cloud regardless of the company size?"He said that "the good points of the cloud" should be actively used, such as eliminating the effort to operate infrastructure.Uehara also said that he agreed, and commented, "I don't think it's time to think about disadvantages now, as the merits of the cloud will increase further."

　When asked, "What if you choose a cloud service freely at your own discretion instead of a company judgment?"In the current cloud market, AWS is the de facto standard, and the service lineup is abundant.First of all, it will be such a choice.

　On the other hand, when asked, "Do you think it would be essential to wear multi -cloud skills as an engineer?"You can enjoy more benefits by wearing "multi -cloud skills" that can be selected flexibly according to the contents of the project.

　"Recently, each of the cloud companies has its own benefits, and for example, if it is a project that uses Oracle Database, I feel that the market situation is gradually changing, such as selecting OCI.I think it depends on your personal personality, but by learning about multiple clouds, you can "increase drawers", I think you can become an engineer who can go wherever you go "(Mr. Omori).

　"The role of the system integrator is to talk with customers and make optimal proposals according to the needs. If it is AWS, I will use it, otherwise it is cost advantage.We will give you comparative materials such as past achievements and choose which one to use. OCI is still in the stage of gaining achievements, but in any case, engineers touch the multi -cloud to some extent and acquire skills.I think it is necessary to wear it "(Mr. Uehara)

* * *

　Recently, the need to work on multi -clouds is strongly shouting because many companies have noticed that a single cloud alone cannot cover everything.Therefore, the engineer who uses the cloud to use, and the engineer who uses it will be required to have a "connoisseur" for multi -cloud.It is necessary to touch various clouds to grasp their features and acquire the skills that can be actually used.

　In the session, Omori of Atomitech said, "We are looking forward to the service that makes use of the merits of" later clouds "."OCIs have the strengths that can develop services based on the high cost performance, the second -generation (GEN2) data center infrastructure, and the complete compatibility with the on -premises environment.By accelerating the addition of services and accumulating the unique features of the OCI, the "necessity of choosing OCI" will increase in the multi -cloud era.
