java - Logic Architectural Model: references for further understanding? -


i having trouble understanding logical architectural model , how relates service orientated architecture. e.g:

model diagram

i not general principle behind , how each of services connect (i.e. talk 1 another). have links/resources understanding this?

the link have found far ibm website has not been help.

i confused physical architecture model of soa works? , main components are?

the best place find you're looking reading ibm soa foundation: architectural introduction whitepaper ibm. excellent resource understand patterns: soa foundation service creation scenario.

i try explain of boxes, maybe in over-simplified way:

  • interaction services presentation logic , allowing user access solution. typical component in layer portal application, in ibm world means ibm websphere portal solution.
  • process services services in charge of composing logic, , ibm-way through business process flows deployed on ibm websphere process server.
  • business application services business logic is: these components composed flows in process service layer. in typical solution components here web services deployed in ibm websphere application server.
  • information services -according book- "data logic" resides, including business intelligence components. believe ibm db2 database has several functionality handle this.
  • access services wrappers expose legacy applications through web services.
  • partner services gives solution capabilities interact external partners/suppliers. give simple example, here can have services allow consumption of services exposed external supplier, become in case partner service provider.

the remaining boxes supporting elements of architecture, , not related business design, although they're important ibm soa foundation.

in relation physical architecture model, ibm soa foundation: architectural introduction describes , has nice diagram of it:

enter image description here

as logical architecture model, i'll describe of boxes:

  • every service request traverse esb server.
  • using gateway, can select services visible internet.
  • the firewall server limits protocols , ports visible outside intranet, allowing creation of de-militarized zone (dmz)
  • the proxy server has several responsibilities. can mention page caching , workload distribution among others.
  • the portal server hosts interaction services .
  • the process server hosts process services.
  • the application server hosts business application services.
  • the security server manages identity , authorization management.
  • the management server monitors entire service environment.

how to proxy from https to http with lighttpd -

i have internal site (192.168.2.1) accessible http on different server run public web-server using lighttpd. can make internal site accessible outside work follows $http["host"] == "internal.example.com" { ... proxy.server = ( "" => ( "internal" => ( "host" => "192.168.2.1", "port" => 8000 ) ) } this works, use https outside world. question is, how can proxy going https http ? i've tried this: $server["socket"] == ":443" { $http["host"] == "internal.example.com" { ... proxy.server = ( "" => ( "internal" => ( "host" => "http://192.168.2.1", "port" => 8000 ) ) } } but doesn't seem wor...

android - Automated my builds -

i have multiple app , android project want automated in build , release sequence. have ant script build , create apk of app. want have 1 script or ant file start build sequence app. maybe don't konw search, can't find easy documentation on ant. the point of use jenkins ant (or maven, i'm not sure of difference between them now) automated build sequence when people commit on project. any int appreciated maven dependencies (over ant) don't need pass around jars. recommend maven on ant day. syntax , overall process easier understand, @ end of both build tools. if able to, more recommend upgrading gradle. easy create different build types , create them ./gradlew assemble here project jake wharton can see power of gradle. there release , debug build, can make lot more if like. https://github.com/jakewharton/u2020 here android docs gradle http://tools.android.com/tech-docs/new-build-system/user-guide . if can't find looking here, check out main grad...
