Preface ：

It has been more than a year since Tencent cloud lightweight application server went online , It has gained more recognition . For some individual developers and small and medium-sized enterprises , Relative to specialty （ complex ） Of CVM, Lightweight application servers are more suitable for them . For some CVM The old customers , Turning to lightweight application servers is also a good choice , But at the same time, other problems such as server migration are also a lot of trouble .

Recently, lightweight application servers have also launched a new mirroring function , Through the lightweight application server's mirroring function , from CVM To Lighthouse Offline migration of business .

CVM Cloud server *1,Lighthouse Lightweight application servers *1, Both hosts have chosen Guangzhou

PS： The hard disk space of the target migration host must be greater than or equal to that of the migrated host

Operation experience ：

CVM Create images and share ：

stay CVM Create an image in the details page （ This process CVM It will shut down and be used to create images ）

stay CVM After the image is created, you need to share the image in the lightweight application server

Lighthouse Install the shared image

stay CVM After sharing related images, you can view the shared images on the lightweight application server image page .

Redo the application on the target lightweight application server , Select personal image in image selection ---- Sharing the mirror

Select the business migration image we just created , Installation

Wait a while , The image reset of this computer is completed , The whole process takes less than ten minutes , The relevant data of ECS is from CVM Migrate to Lighthouse.

Of course ,CVM be relative to Lighthouse It is more suitable for professional and large enterprise application scenarios , Same principle , Transfer personal business from Lighthouse Migrate to CVM It's OK, too . Select the corresponding virtual machine , Making mirrors , In a lightweight application server, the image page shares the image to CVM Pages can also be implemented from lightweight application servers to CVM Offline migration of business .

Written in the back ：

As a new online function , On the whole, image sharing is used to realize from CVM To Lighthouse Offline business migration , It almost seems like a kind of “ Curve of national salvation ” Is also a feasible way , Let it be more CVM Users are more confident to choose Lighthouse, Avoided “ Start over again ” The trouble of , Spend more time efficiently .

Of course, sharing through images also has certain limitations ： In account No CVM And Lighthouse Sharing between, not Lighthouse Sharing between accounts 、 You should pay attention to the size of hard disk space （ As shown in the figure ）、 Potential migration problems are inevitable ... These all need users' attention before use , After passing the test, there are a lot less at this stage Bug, take CVM Some mature technologies are applied in Lighthouse It's also desirable in practice .

Lighthouse and CVM Through the intranet 、 Mirror image 、 Automation assistant and other functions are closely linked again , Meet different needs in different application scenarios , Gradually new functions are added for individual developers 、 Enterprise users will be a blessing .
